Introduction

In this assessment you are configuring a network that is using EtherChannel and routing between VLANs. For the sake of time, you will not be asked to perform all configurations on all network devices as you may be required to do in a real network or other assessment. Instead, you will use the skills and knowledge that you have learned in the labs in this course to configure the router and switches in the topology. In addition to EtherChannel and inter-VLAN routing, this task involves creating VLANs and trunks, and performing basic router and switch configuration.

You are required to configure host default gateways; however host addresses are preconfigured.

You will practice and be assessed on the following skills:

Configuration of initial settings on a router.
Configuration of initial settings on a switch, including SVI and SSH.
Configuration of VLANs.
Configuration of switchport VLAN membership.
EtherChannel configuration.
Troubleshooting VLANs.
Configuration of static trunking and DTP.
Configuration of routing between VLANs on a Layer 3 switch.
Configuration of router-on-a-stick inter- VLAN routing on a router.
Configure default gateways on hosts.

Background / Scenario

A corporation is planning to implement EtherChannel and a new VLAN design in order to make the network more efficient. You have been asked to work on a design and prototype of the new network. You have created the logical topology and now need to configure the devices in order to evaluate the design. You will configure VLANs and access port VLAN membership on access layer switches. You will also configure EtherChannel and trunking. Finally, you will configure a router and a Layer 3 switch to route between VLANs. Some addressing had already been configured.

Instructions

Part 1: Basic Router Configuration

Step 1: Configure router Edge-Router with required settings.

a. Open a command window on router Edge-Router and move to privileged EXEC mode.

b. Copy and paste the following configuration into the Edge-Router router CLI.

ip route 192.168.10.0 255.255.255.0 GigabitEthernet0/0/0

ip route 192.168.20.0 255.255.255.0 GigabitEthernet0/0/0

ip route 192.168.30.0 255.255.255.0 GigabitEthernet0/0/0

ip route 192.168.99.0 255.255.255.240 GigabitEthernet0/0/0

Be sure to press the <Enter> key after the last line to return to privileged EXEC mode prompt.

c. Configure the following settings on the router:

The enable secret password.
A console password
Remote access to the VTY lines.
A banner MOTD message.
The device hostname according to the value in the addressing table.
All clear text passwords should be encrypted.
Interface addressing on G0/0/0 and S0/1/0.
Interface descriptions on G0/0/0 and S0/1/0.

Router(config)#no ip domain lookup
Router(config)#enable secret class

Router(config)#line console 0
Router(config-line)#password cisco
Router(config-line)#login
Router(config-line)#exit

Router(config)#line vty 0 4
Router(config-line)#password cisco
Router(config-line)#login
Router(config-line)#exit

Router(config)#banner motd #Authorized Access Only!#

Router(config)#hostname Edge-Router

Edge-Router(config)#service password-encryption

Edge-Router(config)#interface g0/0/0
Edge-Router(config-if)#ip address 192.168.0.1 255.255.255.0
Edge-Router(config-if)#no shutdown
Edge-Router(config-if)#description Link to Sciences LAN
Edge-Router(config-if)#exit

Edge-Router(config)#interface s0/1/0
Edge-Router(config-if)#ip address 209.165.201.2 255.255.255.252
Edge-Router(config-if)#no shutdown
Edge-Router(config-if)#description Link to Internet
Edge-Router(config-if)#exit

Note: Be sure to make a record of the passwords that you create.

Part 2: Basic Switch Configuration

Step 1: Configure Remote Management Addressing

a. Configure SVI 99 on switch Sw-C with IP addressing according to the Addressing Table.
b. The Sw-C switch SVI should be reachable from other networks.

Sw-C(config)#interface vlan 99
Sw-C(config-if)#ip address 192.168.99.18 255.255.255.240
Sw-C(config-if)#no shutdown
Sw-C(config-if)#exit
Sw-C(config)#
Sw-C(config)#ip default-gateway 192.168.99.17

Step 2: Configure Secure Remote Access

On switch Sw-C, configure SSH as follows:

Username: admin password: C1sco123!
Modulus bits 1024
All VTY lines should accept SSH connections only
Connections should require the previously configured username and password.
IP domain name: acad.pt

Sw-C(config)#ip domain-name acad.pt
Sw-C(config)#crypto key generate rsa
How many bits in the modulus [512]: 1024

Sw-C(config)#username admin privilege 15 secret C1sco123!
Sw-C(config)#enable secret C1sco123!
Sw-C(config)#line vty 0 15
Sw-C(config-line)#transport input ssh
Sw-C(config-line)#login local
Sw-C(config-line)#exit
Sw-C(config)#ip ssh version 2

Part 3: VLAN Configuration

Step 1: Configure VLANs according to the VLAN table.

Use the VLAN Table to create and name the VLANs on the appropriate switches.

Part 4: EtherChannel and Trunking Configuration

EtherChannel Port Assignments Table

Channel Group	Devices in Groups	Ports in Group
1	L3-SW1	G1/0/1, G1/0/2
1	Sw-A	G0/1, G0/2
2	L3-SW1	G1/0/3, G1/0/4
2	Sw-B	G0/1, G0/2
3	Sw-A	F0/5, F0/6
3	Sw-B	F0/5, F0/6

Step 1: Configure EtherChannels

Create EtherChannels according to the EtherChannel Port Assignments Table. Use the Cisco LACP protocol. Both sides of the channel should attempt to negotiate the link protocol.

L3-SW1

L3-SW1(config)#interface range g1/0/1-2
L3-SW1(config-if-range)#channel-group 1 mode active
L3-SW1(config-if-range)#exit
L3-SW1(config)#
L3-SW1(config)#interface range g1/0/3-4
L3-SW1(config-if-range)#channel-group 2 mode active
L3-SW1(config-if-range)#exit

Sw-A

Sw-A(config)#interface range g0/1-2
Sw-A(config-if-range)#channel-group 1 mode active
Sw-A(config-if-range)#exit
Sw-A(config)#
Sw-A(config)#interface range f0/5-6
Sw-A(config-if-range)#channel-group 3 mode active
Sw-A(config-if-range)#exit

Sw-B

Sw-B(config)#interface range g0/1-2
Sw-B(config-if-range)#channel-group 2 mode active
Sw-B(config-if-range)#exit
Sw-B(config)#
Sw-B(config)#interface range f0/5-6
Sw-B(config-if-range)#channel-group 3 mode active
Sw-B(config-if-range)#exit

Step 2: Configure Trunking on the EtherChannels

a. Configure the port channel interfaces as static trunks. Disable DTP negotiation on all trunks.
b. Troubleshoot any issues that prevent the formation of the EtherChannels.

L3-SW1

L3-SW1(config)#interface port-channel 1
L3-SW1(config-if)#switchport mode trunk
L3-SW1(config-if)#switchport trunk allowed vlan 10,20,30
L3-SW1(config-if)#exit
L3-SW1(config)#
L3-SW1(config)#interface port-channel 2
L3-SW1(config-if)#switchport mode trunk
L3-SW1(config-if)#switchport trunk allowed vlan 10,20,30
L3-SW1(config-if)#exit

Sw-A

Sw-A(config)#interface port-channel 1
Sw-A(config-if)#switchport mode trunk 
Sw-A(config-if)#switchport nonegotiate
Sw-A(config-if)#exit
Sw-A(config)#
Sw-A(config)#interface port-channel 3
Sw-A(config-if)#switchport mode trunk 

Sw-A(config-if)#switchport nonegotiate
Sw-A(config-if)#exit

Sw-B

Sw-B(config)#interface port-channel 2
Sw-B(config-if)#switchport mode trunk 
Sw-B(config-if)#switchport nonegotiate
Sw-B(config-if)#exit
Sw-B(config)#
Sw-B(config)#interface port-channel 3
Sw-B(config-if)#switchport mode trunk 

Sw-B(config-if)#switchport nonegotiate
Sw-B(config-if)#exit

Note: Packet Tracer requires configuration of trunking and DTP mode on both portchannel interfaces and the component physical interfaces.

Step 3: Configure a static trunk uplink

a. On the Sw-C switch, configure the port that is connected to Edge-Router G0/0/0 as a static trunk.
b. Configure the Management VLAN as the native VLAN.
c. Disable DTP on the port.

Sw-C

Sw-C(config)#interface g0/1
Sw-C(config-if)#switchport mode trunk
Sw-C(config-if)#switchport nonegotiate
Sw-C(config-if)#switchport trunk native vlan 99
Sw-C(config-if)#switchport trunk allowed vlan 40,50,60,99
Sw-C(config-if)#exit

Part 5: Configure Inter-VLAN Routing

Step 1: Configure inter-VLAN routing on the Layer 3 switch.

a. Configure Inter-VLAN routing on the L3-SW1 Layer 3 switch for all VLANs in the VLAN Table that are configured on L3-SW1.
b. Configure the switchport on L3-SW1 that is connected to Edge-Router with an IP address as shown in the Addressing Table.

L3-SW1

L3-SW1(config)#ip routing
L3-SW1(config)#interface g1/1/1
L3-SW1(config-if)#no switchport
L3-SW1(config-if)#ip address 192.168.0.2 255.255.255.0

Step 2: Configure router-on-a-stick inter-VLAN routing on a router.

a. Configure inter-VLAN routing on Edge-Router for all the VLANs that are configured on the Sw-C switch. Use the information in the Addressing Table.
b. Be sure to configure descriptions of all interfaces.

Edge-Router

Edge-Router(config)#interface g0/0/1
Edge-Router(config-if)#no shutdown 
Edge-Router(config)#interface g0/0/1.40
Edge-Router(config-subif)#description "Gateway for VLAN40"

Edge-Router(config-subif)#ip address 192.168.99.17 255.255.255.240
Edge-Router(config-subif)#exit

Step 3: Configure default gateways on hosts.

a. Configure default gateway addresses on all hosts on the LANs.

Default gateway on WS-1.1 and WS-1.4: 192.168.10.1
Default gateway on WS-1.2 and WS-1.5: 192.168.20.1
Default gateway on WS-1.3 and WS-1.6: 192.168.30.1

Default gateway on WS-2.1: 192.168.40.1
Default gateway on WS-2.2: 192.168.50.1
Default gateway on WS-2.3: 192.168.60.1
Default gateway on Management PC: 192.168.99.17

b. Verify connectivity between all hosts on both LANs with each other and the Outside Server server.
c. Verify that a host can connect to the SVI of switch Sw-C over SSH.

Background / Scenario

Instructions

Part 1: Basic Router Configuration

Step 1: Configure router Edge-Router with required settings.

a. Open a command window on router Edge-Router and move to privileged EXEC mode.

b. Copy and paste the following configuration into the Edge-Router router CLI.

ip route 172.31.10.0 255.255.255.0 GigabitEthernet0/0/0

ip route 172.31.20.0 255.255.255.0 GigabitEthernet0/0/0

ip route 172.31.30.0 255.255.255.0 GigabitEthernet0/0/0

ip route 172.31.99.0 255.255.255.240 GigabitEthernet0/0/0

Be sure to press the <Enter> key after the last line to return to privileged EXEC mode prompt.

c. Configure the following settings on the router:

The enable secret password.
A console password
Remote access to the VTY lines.
A banner MOTD message.
The device hostname according to the value in the addressing table.
All clear text passwords should be encrypted.
Interface addressing on G0/0/0 and S0/1/0.
Interface descriptions on G0/0/0 and S0/1/0.

Router(config)#no ip domain lookup
Router(config)#enable secret class

Router(config)#line console 0
Router(config-line)#password cisco
Router(config-line)#login
Router(config-line)#exit

Router(config)#line vty 0 4
Router(config-line)#password cisco
Router(config-line)#login
Router(config-line)#exit

Router(config)#banner motd #Authorized Access Only!#

Router(config)#hostname Edge-Router

Edge-Router(config)#service password-encryption

Edge-Router(config)#interface g0/0/0
Edge-Router(config-if)#ip address 172.31.0.1 255.255.255.0
Edge-Router(config-if)#no shutdown
Edge-Router(config-if)#description Link to Sciences LAN
Edge-Router(config-if)#exit

Edge-Router(config)#interface s0/1/0
Edge-Router(config-if)#ip address 209.165.201.2 255.255.255.252
Edge-Router(config-if)#no shutdown
Edge-Router(config-if)#description Link to Internet
Edge-Router(config-if)#exit

Note: Be sure to make a record of the passwords that you create.

Part 2: Basic Switch Configuration

Step 1: Configure Remote Management Addressing

a. Configure SVI 99 on switch Sw-C with IP addressing according to the Addressing Table.
b. The Sw-C switch SVI should be reachable from other networks.

Sw-C(config)#interface vlan 99
Sw-C(config-if)#ip address 172.31.99.18 255.255.255.240
Sw-C(config-if)#no shutdown
Sw-C(config-if)#exit
Sw-C(config)#
Sw-C(config)#ip default-gateway 172.31.99.17

Step 2: Configure Secure Remote Access

On switch Sw-C, configure SSH as follows:

Username: admin password: C1sco123!
Modulus bits 1024
All VTY lines should accept SSH connections only
Connections should require the previously configured username and password.
IP domain name: acad.pt

Sw-C(config)#ip domain-name acad.pt
Sw-C(config)#crypto key generate rsa
How many bits in the modulus [512]: 1024

Sw-C(config)#username admin privilege 15 secret C1sco123!
Sw-C(config)#enable secret C1sco123!
Sw-C(config)#line vty 0 15
Sw-C(config-line)#transport input ssh
Sw-C(config-line)#login local
Sw-C(config-line)#exit
Sw-C(config)#ip ssh version 2

Part 3: VLAN Configuration

Step 1: Configure VLANs according to the VLAN table.

Use the VLAN Table to create and name the VLANs on the appropriate switches.

Part 4: EtherChannel and Trunking Configuration

EtherChannel Port Assignments Table

Channel Group	Devices in Groups	Ports in Group
1	L3-SW1	G1/0/1, G1/0/2
1	Sw-A	G0/1, G0/2
2	L3-SW1	G1/0/3, G1/0/4
2	Sw-B	G0/1, G0/2
3	Sw-A	F0/5, F0/6
3	Sw-B	F0/5, F0/6

Step 1: Configure EtherChannels

Create EtherChannels according to the EtherChannel Port Assignments Table. Use the Cisco LACP protocol. Both sides of the channel should attempt to negotiate the link protocol.

L3-SW1

L3-SW1(config)#interface range g1/0/1-2
L3-SW1(config-if-range)#channel-group 1 mode active
L3-SW1(config-if-range)#exit
L3-SW1(config)#
L3-SW1(config)#interface range g1/0/3-4
L3-SW1(config-if-range)#channel-group 2 mode active
L3-SW1(config-if-range)#exit

Sw-A

Sw-A(config)#interface range g0/1-2
Sw-A(config-if-range)#channel-group 1 mode active
Sw-A(config-if-range)#exit
Sw-A(config)#
Sw-A(config)#interface range f0/5-6
Sw-A(config-if-range)#channel-group 3 mode active
Sw-A(config-if-range)#exit

Sw-B

Sw-B(config)#interface range g0/1-2
Sw-B(config-if-range)#channel-group 2 mode active
Sw-B(config-if-range)#exit
Sw-B(config)#
Sw-B(config)#interface range f0/5-6
Sw-B(config-if-range)#channel-group 3 mode active
Sw-B(config-if-range)#exit

Step 2: Configure Trunking on the EtherChannels

a. Configure the port channel interfaces as static trunks. Disable DTP negotiation on all trunks.
b. Troubleshoot any issues that prevent the formation of the EtherChannels.

L3-SW1

L3-SW1(config)#interface port-channel 1
L3-SW1(config-if)#switchport mode trunk
L3-SW1(config-if)#switchport trunk allowed vlan 10,20,30
L3-SW1(config-if)#exit
L3-SW1(config)#
L3-SW1(config)#interface port-channel 2
L3-SW1(config-if)#switchport mode trunk
L3-SW1(config-if)#switchport trunk allowed vlan 10,20,30
L3-SW1(config-if)#exit

Sw-A

Sw-A(config)#interface port-channel 1
Sw-A(config-if)#switchport mode trunk 
Sw-A(config-if)#switchport nonegotiate
Sw-A(config-if)#exit
Sw-A(config)#
Sw-A(config)#interface port-channel 3
Sw-A(config-if)#switchport mode trunk 

Sw-A(config-if)#switchport nonegotiate
Sw-A(config-if)#exit

Sw-B

Sw-B(config)#interface port-channel 2
Sw-B(config-if)#switchport mode trunk 
Sw-B(config-if)#switchport nonegotiate
Sw-B(config-if)#exit
Sw-B(config)#
Sw-B(config)#interface port-channel 3
Sw-B(config-if)#switchport mode trunk 

Sw-B(config-if)#switchport nonegotiate
Sw-B(config-if)#exit

Note: Packet Tracer requires configuration of trunking and DTP mode on both portchannel interfaces and the component physical interfaces.

Step 3: Configure a static trunk uplink

a. On the Sw-C switch, configure the port that is connected to Edge-Router G0/0/0 as a static trunk.
b. Configure the ADMIN VLAN as the native VLAN.
c. Disable DTP on the port.

Sw-C

Sw-C(config)#interface g0/1
Sw-C(config-if)#switchport mode trunk
Sw-C(config-if)#switchport nonegotiate
Sw-C(config-if)#switchport trunk native vlan 99
Sw-C(config-if)#switchport trunk allowed vlan 40,50,60,99
Sw-C(config-if)#exit

Part 5: Configure Inter-VLAN Routing

Step 1: Configure inter-VLAN routing on the Layer 3 switch.

L3-SW1

L3-SW1(config)#ip routing
L3-SW1(config)#interface g1/1/1
L3-SW1(config-if)#no switchport
L3-SW1(config-if)#ip address 172.31.0.2 255.255.255.0

Step 2: Configure router-on-a-stick inter-VLAN routing on a router.

Edge-Router

Edge-Router(config)#interface g0/0/1
Edge-Router(config-if)#no shutdown 
Edge-Router(config)#interface g0/0/1.40

Background / Scenario

Instructions

Part 1: Basic Router Configuration

Step 1: Configure router RTR-1 with required settings.

a. Open a command window on router RTR-1 and move to privileged EXEC mode.

b. Copy and paste the following configuration into the RTR-1 router CLI.

ip route 192.168.10.0 255.255.255.0 GigabitEthernet0/0/0

ip route 192.168.20.0 255.255.255.0 GigabitEthernet0/0/0

ip route 192.168.30.0 255.255.255.0 GigabitEthernet0/0/0

ip route 192.168.99.0 255.255.255.240 GigabitEthernet0/0/0

Be sure to press the <Enter> key after the last line to return to privileged EXEC mode prompt.

c. Configure the following settings on the router:

The enable secret password.
A console password
Remote access to the VTY lines.
A banner MOTD message.
The device hostname according to the value in the addressing table.
All clear text passwords should be encrypted.
Interface addressing on G0/0/0 and S0/1/0.
Interface descriptions on G0/0/0 and S0/1/0.

RTR-1(config-if)#description Link to Internet
RTR-1(config-if)#exit

Note: Be sure to make a record of the passwords that you create.

Part 2: Basic Switch Configuration

Step 1: Configure Remote Management Addressing

a. Configure SVI 99 on switch SW-3 with IP addressing according to the Addressing Table.
b. The SW-3 switch SVI should be reachable from other networks.

SW-3(config)#interface vlan 99
SW-3(config-if)#ip address 192.168.99.18 255.255.255.240
SW-3(config-if)#no shutdown
SW-3(config-if)#exit
SW-3(config)#
SW-3(config)#ip default-gateway 192.168.99.17

Step 2: Configure Secure Remote Access

On switch SW-3, configure SSH as follows:

Username: admin password: C1sco123!
Modulus bits 1024
All VTY lines should accept SSH connections only
Connections should require the previously configured username and password.
IP domain name: acad.pt

SW-3(config)#ip domain-name acad.pt
SW-3(config)#crypto key generate rsa
How many bits in the modulus [512]: 1024

SW-3(config)#username admin privilege 15 secret C1sco123!
SW-3(config)#enable secret C1sco123!
SW-3(config)#line vty 0 15
SW-3(config-line)#transport input ssh
SW-3(config-line)#login local
SW-3(config-line)#exit
SW-3(config)#ip ssh version 2

Part 3: VLAN Configuration

Step 1: Configure VLANs according to the VLAN table.

Use the VLAN Table to create and name the VLANs on the appropriate switches.

Step 2: Configure Trunking on the EtherChannels

a. Configure the port channel interfaces as static trunks. Disable DTP negotiation on all trunks.
b. Troubleshoot any issues that prevent the formation of the EtherChannels.

MSW-1

MSW-1(config)#interface port-channel 1
MSW-1(config-if)#switchport mode trunk
MSW-1(config-if)#switchport trunk allowed vlan 10,20,30
MSW-1(config-if)#exit
MSW-1(config)#
MSW-1(config)#interface port-channel 2
MSW-1(config-if)#switchport mode trunk
MSW-1(config-if)#switchport trunk allowed vlan 10,20,30
MSW-1(config-if)#exit

SW-1

SW-1(config)#interface port-channel 1
SW-1(config-if)#switchport mode trunk 
SW-1(config-if)#switchport nonegotiate
SW-1(config-if)#exit
SW-1(config)#
SW-1(config)#interface port-channel 3
SW-1(config-if)#switchport mode trunk 

SW-1(config-if)#switchport nonegotiate
SW-1(config-if)#exit

SW-2

SW-2(config)#interface port-channel 2
SW-2(config-if)#switchport mode trunk 
SW-2(config-if)#switchport nonegotiate
SW-2(config-if)#exit
SW-2(config)#
SW-2(config)#interface port-channel 3
SW-2(config-if)#switchport mode trunk 

SW-2(config-if)#switchport nonegotiate
SW-2(config-if)#exit

Note: Packet Tracer requires configuration of trunking and DTP mode on both portchannel interfaces and the component physical interfaces.

Step 3: Configure a static trunk uplink

a. On the SW-3 switch, configure the port that is connected to RTR-1 G0/0/0 as a static trunk.
b. Configure the ADMIN VLAN as the native VLAN.
c. Disable DTP on the port.

SW-3

SW-3(config)#interface g0/1
SW-3(config-if)#switchport mode trunk
SW-3(config-if)#switchport nonegotiate
SW-3(config-if)#switchport trunk native vlan 99
SW-3(config-if)#switchport trunk allowed vlan 40,50,60,99
SW-3(config-if)#exit

Part 5: Configure Inter-VLAN Routing

Step 1: Configure inter-VLAN routing on the Layer 3 switch.

a. Configure Inter-VLAN routing on the MSW-1 Layer 3 switch for all VLANs in the VLAN Table that are configured on MSW-1.
b. Configure the switchport on MSW-1 that is connected to RTR-1 with an IP address as shown in the Addressing Table.

MSW-1

MSW-1(config)#ip routing
MSW-1(config)#interface g1/1/1
MSW-1(config-if)#no switchport
MSW-1(config-if)#ip address 192.168.0.2 255.255.255.0

Step 2: Configure router-on-a-stick inter-VLAN routing on a router.

a. Configure inter-VLAN routing on RTR-1 for all the VLANs that are configured on the SW-3 switch. Use the information in the Addressing Table.
b. Be sure to configure descriptions of all interfaces.

RTR-1

RTR-1(config)#interface g0/0/1
RTR-1(config-if)#no shutdown 
RTR-1(config)#interface g0/0/1.40
RTR-1(config-subif)#description "Gateway for VLAN40"
RTR-1(config-subif)#encapsulation dot1q 40
RTR-1(config-subif)#ip address 192.168.40.1 255.255.255.0
RTR-1(config-subif)#exit
RTR-1(config)#interface g0/0/1.50
RTR-1(config-subif)#description "Gateway for VLAN50"
RTR-1(config-subif)#encapsulation dot1q 50

RTR-1(config-subif)#exit
RTR-1(config)#interface g0/0/1.60
RTR-1(config-subif)#description "Gateway for VLAN60"
RTR-1(config-subif)#encapsulation dot1q 60
RTR-1(config-subif)#ip address 192.168.60.1 255.255.255.0
RTR-1(config-subif)#exit
RTR-1(config)#interface g0/0/1.99
RTR-1(config-subif)#description "Gateway for VLAN99"
RTR-1(config-subif)#encapsulation dot1q 99 native
RTR-1(config-subif)#ip address 192.168.99.17 255.255.255.240
RTR-1(config-subif)#exit

Step 3: Configure default gateways on hosts.

a. Configure default gateway addresses on all hosts on the LANs.

Default gateway on PC1 and PC4: 192.168.10.1
Default gateway on PC2 and PC5: 192.168.20.1
Default gateway on PC3 and PC6: 192.168.30.1

Default gateway on PC7: 192.168.40.1
Default gateway on PC8: 192.168.50.1
Default gateway on PC9: 192.168.60.1
Default gateway on PC99: 192.168.99.17

b. Verify connectivity between all hosts on both LANs with each other and the Internet Server server.
c. Verify that a host can connect to the SVI of switch SW-3 over SSH.

Background / Scenario

Instructions

Part 1: Basic Router Configuration

Step 1: Configure router RTR-1 with required settings.

a. Open a command window on router RTR-1 and move to privileged EXEC mode.

b. Copy and paste the following configuration into the RTR-1 router CLI.

ip route 192.168.10.0 255.255.255.0 GigabitEthernet0/0/0

ip route 192.168.20.0 255.255.255.0 GigabitEthernet0/0/0

ip route 192.168.30.0 255.255.255.0 GigabitEthernet0/0/0

ip route 192.168.99.0 255.255.255.240 GigabitEthernet0/0/0

Be sure to press the <Enter> key after the last line to return to privileged EXEC mode prompt.

c. Configure the following settings on the router:

The enable secret password.
A console password
Remote access to the VTY lines.
A banner MOTD message.
The device hostname according to the value in the addressing table.
All clear text passwords should be encrypted.
Interface addressing on G0/0/0 and S0/1/0.
Interface descriptions on G0/0/0 and S0/1/0.

RTR-1(config-if)#exit

Note: Be sure to make a record of the passwords that you create.

Part 2: Basic Switch Configuration

Step 1: Configure Remote Management Addressing

a. Configure SVI 99 on switch SW-3 with IP addressing according to the Addressing Table.
b. The SW-3 switch SVI should be reachable from other networks.

SW-3(config)#interface vlan 99
SW-3(config-if)#ip address 192.168.99.18 255.255.255.240
SW-3(config-if)#no shutdown
SW-3(config-if)#exit
SW-3(config)#
SW-3(config)#ip default-gateway 192.168.99.17

Step 2: Configure Secure Remote Access

On switch SW-3, configure SSH as follows:

Username: admin password: C1sco123!
Modulus bits 1024
All VTY lines should accept SSH connections only
Connections should require the previously configured username and password.
IP domain name: acad.pt

SW-3(config)#ip domain-name acad.pt
SW-3(config)#crypto key generate rsa
How many bits in the modulus [512]: 1024

SW-3(config)#username admin privilege 15 secret C1sco123!
SW-3(config)#enable secret C1sco123!
SW-3(config)#line vty 0 15
SW-3(config-line)#transport input ssh
SW-3(config-line)#login local
SW-3(config-line)#exit
SW-3(config)#ip ssh version 2

Part 3: VLAN Configuration

Step 1: Configure VLANs according to the VLAN table.

Use the VLAN Table to create and name the VLANs on the appropriate switches.

Part 4: EtherChannel and Trunking Configuration

EtherChannel Port Assignments Table

Channel Group	Devices in Groups	Ports in Group
1	MSW-1	G1/0/1, G1/0/2
1	SW-1	G0/1, G0/2
2	MSW-1	G1/0/3, G1/0/4
2	SW-2	G0/1, G0/2
3	SW-1	F0/5, F0/6
3	SW-2	F0/5, F0/6

Step 1: Configure EtherChannels

Create EtherChannels according to the EtherChannel Port Assignments Table. Use the Cisco LACP protocol. Both sides of the channel should attempt to negotiate the link protocol.

MSW-1

MSW-1(config)#interface range g1/0/1-2
MSW-1(config-if-range)#channel-group 1 mode active
MSW-1(config-if-range)#exit
MSW-1(config)#
MSW-1(config)#interface range g1/0/3-4
MSW-1(config-if-range)#channel-group 2 mode active
MSW-1(config-if-range)#exit

SW-1

SW-1(config)#interface range g0/1-2
SW-1(config-if-range)#channel-group 1 mode active
SW-1(config-if-range)#exit
SW-1(config)#
SW-1(config)#interface range f0/5-6
SW-1(config-if-range)#channel-group 3 mode active
SW-1(config-if-range)#exit

SW-2

SW-2(config)#interface range g0/1-2
SW-2(config-if-range)#channel-group 2 mode active
SW-2(config-if-range)#exit
SW-2(config)#
SW-2(config)#interface range f0/5-6
SW-2(config-if-range)#channel-group 3 mode active
SW-2(config-if-range)#exit

Step 2: Configure Trunking on the EtherChannels

a. Configure the port channel interfaces as static trunks. Disable DTP negotiation on all trunks.
b. Troubleshoot any issues that prevent the formation of the EtherChannels.

MSW-1

MSW-1(config)#interface port-channel 1
MSW-1(config-if)#switchport mode trunk
MSW-1(config-if)#switchport trunk allowed vlan 10,20,30
MSW-1(config-if)#exit
MSW-1(config)#
MSW-1(config)#interface port-channel 2
MSW-1(config-if)#switchport mode trunk
MSW-1(config-if)#switchport trunk allowed vlan 10,20,30
MSW-1(config-if)#exit

SW-1

SW-1(config)#interface port-channel 1
SW-1(config-if)#switchport mode trunk 
SW-1(config-if)#switchport nonegotiate
SW-1(config-if)#exit
SW-1(config)#
SW-1(config)#interface port-channel 3
SW-1(config-if)#switchport mode trunk 

SW-1(config-if)#switchport nonegotiate
SW-1(config-if)#exit

SW-2

SW-2(config)#interface port-channel 2
SW-2(config-if)#switchport mode trunk 
SW-2(config-if)#switchport nonegotiate
SW-2(config-if)#exit
SW-2(config)#
SW-2(config)#interface port-channel 3
SW-2(config-if)#switchport mode trunk 

SW-2(config-if)#switchport nonegotiate
SW-2(config-if)#exit

Note: Packet Tracer requires configuration of trunking and DTP mode on both portchannel interfaces and the component physical interfaces.

Step 3: Configure a static trunk uplink

a. On the SW-3 switch, configure the port that is connected to RTR-1 G0/0/0 as a static trunk.
b. Configure the NetAdmin VLAN as the native VLAN.
c. Disable DTP on the port.

SW-3

SW-3(config)#interface g0/1
SW-3(config-if)#switchport mode trunk
SW-3(config-if)#switchport nonegotiate
SW-3(config-if)#switchport trunk native vlan 99
SW-3(config-if)#switchport trunk allowed vlan 40,50,60,99
SW-3(config-if)#exit

Part 5: Configure Inter-VLAN Routing

Step 1: Configure inter-VLAN routing on the Layer 3 switch.

MSW-1

MSW-1(config)#ip routing
MSW-1(config)#interface g1/1/1
MSW-1(config-if)#no switchport
MSW-1(config-if)#ip address 192.168.0.2 255.255.255.0

Step 2: Configure router-on-a-stick inter-VLAN routing on a router.

a. Configure inter-VLAN routing on RTR-1 for all the VLANs that are configured on the SW-3 switch. Use the information in the Addressing Table.
b. Be sure to configure descriptions of all interfaces.

RTR-1

RTR-1(config)#interface g0/0/1
RTR-1(config-if)#no shutdown 
RTR-1(config)#interface g0/0/1.40
RTR-1(config-subif)#description "Gateway for VLAN40"
RTR-1(config-subif)#encapsulation dot1q 40
RTR-1(config-subif)#ip address 192.168.40.1 255.255.255.0
RTR-1(config-subif)#exit
RTR-1(config)#interface g0/0/1.50
RTR-1(config-subif)#description "Gateway for VLAN50"
RTR-1(config-subif)#encapsulation dot1q 50
RTR-1(config-subif)#ip address 192.168.50.1 255.255.255.0
RTR-1(config-subif)#exit
RTR-1(config)#interface g0/0/1.60
RTR-1(config-subif)#description "Gateway for VLAN60"
RTR-1(config-subif)#encapsulation dot1q 60
RTR-1(config-subif)#ip address 192.168.60.1 255.255.255.0
RTR-1(config-subif)#exit
RTR-1(config)#interface g0/0/1.99
RTR-1(config-subif)#description "Gateway for VLAN99"
RTR-1(config-subif)#encapsulation dot1q 99 native
RTR-1(config-subif)#ip address 192.168.99.17 255.255.255.240
RTR-1(config-subif)#exit

Step 3: Configure default gateways on hosts.

a. Configure default gateway addresses on all hosts on the LANs.

Default gateway on PC1 and PC4: 192.168.10.1
Default gateway on PC2 and PC5: 192.168.20.1
Default gateway on PC3 and PC6: 192.168.30.1

Default gateway on PC7: 192.168.40.1
Default gateway on PC8: 192.168.50.1
Default gateway on PC9: 192.168.60.1
Default gateway on PC99: 192.168.99.17

b. Verify connectivity between all hosts on both LANs with each other and the Internet Server server.
c. Verify that a host can connect to the SVI of switch SW-3 over SSH.

Background / Scenario

Instructions

Part 1: Basic Router Configuration

Step 1: Configure router RTR-1 with required settings.

a. Open a command window on router RTR-1 and move to privileged EXEC mode.

b. Copy and paste the following configuration into the RTR-1 router CLI.

ip route 172.31.10.0 255.255.255.0 GigabitEthernet0/0/0

ip route 172.31.20.0 255.255.255.0 GigabitEthernet0/0/0

ip route 172.31.30.0 255.255.255.0 GigabitEthernet0/0/0

ip route 172.31.99.0 255.255.255.240 GigabitEthernet0/0/0

Be sure to press the <Enter> key after the last line to return to privileged EXEC mode prompt.

c. Configure the following settings on the router:

The enable secret password.
A console password
Remote access to the VTY lines.
A banner MOTD message.
The device hostname according to the value in the addressing table.
All clear text passwords should be encrypted.
Interface addressing on G0/0/0 and S0/1/0.
Interface descriptions on G0/0/0 and S0/1/0.

RTR-1(config-if)#description Link to Internet
RTR-1(config-if)#exit

Note: Be sure to make a record of the passwords that you create.

Part 2: Basic Switch Configuration

Step 1: Configure Remote Management Addressing

a. Configure SVI 99 on switch SW-3 with IP addressing according to the Addressing Table.
b. The SW-3 switch SVI should be reachable from other networks.

SW-3(config)#interface vlan 99
SW-3(config-if)#ip address 172.31.99.18 255.255.255.240
SW-3(config-if)#no shutdown
SW-3(config-if)#exit
SW-3(config)#
SW-3(config)#ip default-gateway 172.31.99.17

Step 2: Configure Secure Remote Access

On switch SW-3, configure SSH as follows:

Username: admin password: C1sco123!
Modulus bits 1024
All VTY lines should accept SSH connections only
Connections should require the previously configured username and password.
IP domain name: acad.pt

SW-3(config)#ip domain-name acad.pt
SW-3(config)#crypto key generate rsa
How many bits in the modulus [512]: 1024

SW-3(config)#username admin privilege 15 secret C1sco123!
SW-3(config)#enable secret C1sco123!
SW-3(config)#line vty 0 15
SW-3(config-line)#transport input ssh
SW-3(config-line)#login local
SW-3(config-line)#exit
SW-3(config)#ip ssh version 2

Part 3: VLAN Configuration

Step 1: Configure VLANs according to the VLAN table.

Use the VLAN Table to create and name the VLANs on the appropriate switches.

Part 4: EtherChannel and Trunking Configuration

EtherChannel Port Assignments Table

Channel Group	Devices in Groups	Ports in Group
1	MSW-1	G1/0/1, G1/0/2
1	SW-1	G0/1, G0/2
2	MSW-1	G1/0/3, G1/0/4
2	SW-2	G0/1, G0/2
3	SW-1	F0/5, F0/6
3	SW-2	F0/5, F0/6

Step 1: Configure EtherChannels

Create EtherChannels according to the EtherChannel Port Assignments Table. Use the Cisco LACP protocol. Both sides of the channel should attempt to negotiate the link protocol.

MSW-1

MSW-1(config)#interface range g1/0/1-2
MSW-1(config-if-range)#channel-group 1 mode active
MSW-1(config-if-range)#exit
MSW-1(config)#
MSW-1(config)#interface range g1/0/3-4
MSW-1(config-if-range)#channel-group 2 mode active
MSW-1(config-if-range)#exit

SW-1

SW-1(config)#interface range g0/1-2
SW-1(config-if-range)#channel-group 1 mode active
SW-1(config-if-range)#exit
SW-1(config)#
SW-1(config)#interface range f0/5-6
SW-1(config-if-range)#channel-group 3 mode active
SW-1(config-if-range)#exit

SW-2

SW-2(config)#interface range g0/1-2
SW-2(config-if-range)#channel-group 2 mode active
SW-2(config-if-range)#exit
SW-2(config)#
SW-2(config)#interface range f0/5-6
SW-2(config-if-range)#channel-group 3 mode active
SW-2(config-if-range)#exit

Step 2: Configure Trunking on the EtherChannels

a. Configure the port channel interfaces as static trunks. Disable DTP negotiation on all trunks.
b. Troubleshoot any issues that prevent the formation of the EtherChannels.

MSW-1

MSW-1(config)#interface port-channel 1
MSW-1(config-if)#switchport mode trunk
MSW-1(config-if)#switchport trunk allowed vlan 10,20,30
MSW-1(config-if)#exit
MSW-1(config)#
MSW-1(config)#interface port-channel 2
MSW-1(config-if)#switchport mode trunk
MSW-1(config-if)#switchport trunk allowed vlan 10,20,30
MSW-1(config-if)#exit

SW-1

SW-1(config)#interface port-channel 1
SW-1(config-if)#switchport mode trunk 
SW-1(config-if)#switchport nonegotiate
SW-1(config-if)#exit
SW-1(config)#
SW-1(config)#interface port-channel 3
SW-1(config-if)#switchport mode trunk 

SW-1(config-if)#switchport nonegotiate
SW-1(config-if)#exit

SW-2

SW-2(config)#interface port-channel 2
SW-2(config-if)#switchport mode trunk 
SW-2(config-if)#switchport nonegotiate
SW-2(config-if)#exit
SW-2(config)#
SW-2(config)#interface port-channel 3
SW-2(config-if)#switchport mode trunk 

SW-2(config-if)#switchport nonegotiate
SW-2(config-if)#exit

Note: Packet Tracer requires configuration of trunking and DTP mode on both portchannel interfaces and the component physical interfaces.

Step 3: Configure a static trunk uplink

a. On the SW-3 switch, configure the port that is connected to RTR-1 G0/0/0 as a static trunk.
b. Configure the NetAdmin VLAN as the native VLAN.
c. Disable DTP on the port.

SW-3

SW-3(config)#interface g0/1
SW-3(config-if)#switchport mode trunk
SW-3(config-if)#switchport nonegotiate
SW-3(config-if)#switchport trunk native vlan 99
SW-3(config-if)#switchport trunk allowed vlan 40,50,60,99
SW-3(config-if)#exit

Part 5: Configure Inter-VLAN Routing

Step 1: Configure inter-VLAN routing on the Layer 3 switch.

MSW-1

MSW-1(config)#ip routing
MSW-1(config)#interface g1/1/1
MSW-1(config-if)#no switchport
MSW-1(config-if)#ip address 172.31.0.2 255.255.255.0

Step 2: Configure router-on-a-stick inter-VLAN routing on a router.

a. Configure inter-VLAN routing on RTR-1 for all the VLANs that are configured on the SW-3 switch. Use the information in the Addressing Table.
b. Be sure to configure descriptions of all interfaces.

RTR-1

RTR-1(config)#interface g0/0/1
RTR-1(config-if)#no shutdown 
RTR-1(config)#interface g0/0/1.40
RTR-1(config-subif)#description "Gateway for VLAN40"
RTR-1(config-subif)#encapsulation dot1q 40
RTR-1(config-subif)#ip address 172.31.40.1 255.255.255.0
RTR-1(config-subif)#exit
RTR-1(config)#interface g0/0/1.50
RTR-1(config-subif)#description "Gateway for VLAN50"
RTR-1(config-subif)#encapsulation dot1q 50
RTR-1(config-subif)#ip address 172.31.50.1 255.255.255.0
RTR-1(config-subif)#exit
RTR-1(config)#interface g0/0/1.60
RTR-1(config-subif)#description "Gateway for VLAN60"
RTR-1(config-subif)#encapsulation dot1q 60
RTR-1(config-subif)#ip address 172.31.60.1 255.255.255.0
RTR-1(config-subif)#exit
RTR-1(config)#interface g0/0/1.99
RTR-1(config-subif)#description "Gateway for VLAN99"
RTR-1(config-subif)#encapsulation dot1q 99 native
RTR-1(config-subif)#ip address 172.31.99.17 255.255.255.240
RTR-1(config-subif)#exit

Step 3: Configure default gateways on hosts.

a. Configure default gateway addresses on all hosts on the LANs.

Default gateway on PC1 and PC4: 172.31.10.1
Default gateway on PC2 and PC5: 172.31.20.1
Default gateway on PC3 and PC6: 172.31.30.1

Default gateway on PC7: 172.31.40.1
Default gateway on PC8: 172.31.50.1
Default gateway on PC9: 172.31.60.1
Default gateway on PC99: 172.31.99.17

b. Verify connectivity between all hosts on both LANs with each other and the Internet Server server.
c. Verify that a host can connect to the SVI of switch SW-3 over SSH.

Step 1: Configure router R-1 with required settings.

a. Open a command window on router R-1 and move to privileged EXEC mode.

b. Copy and paste the following configuration into the R-1 router CLI.

ip route 172.31.10.0 255.255.255.0 GigabitEthernet0/0/0

ip route 172.31.20.0 255.255.255.0 GigabitEthernet0/0/0

ip route 172.31.30.0 255.255.255.0 GigabitEthernet0/0/0

ip route 172.31.99.0 255.255.255.240 GigabitEthernet0/0/0

Be sure to press the <Enter> key after the last line to return to privileged EXEC mode prompt.

c. Configure the following settings on the router:

The enable secret password.
A console password
Remote access to the VTY lines.
A banner MOTD message.
The device hostname according to the value in the addressing table.
All clear text passwords should be encrypted.
Interface addressing on G0/0/0 and S0/1/0.
Interface descriptions on G0/0/0 and S0/1/0.

Part 2: Basic Switch Configuration

Step 1: Configure Remote Management Addressing

a. Configure SVI 99 on switch S-3 with IP addressing according to the Addressing Table.
b. The S-3 switch SVI should be reachable from other networks.

S-3(config)#interface vlan 99
S-3(config-if)#ip address 172.31.99.18 255.255.255.240
S-3(config-if)#no shutdown
S-3(config-if)#exit
S-3(config)#
S-3(config)#ip default-gateway 172.31.99.17

Step 2: Configure Secure Remote Access

On switch S-3, configure SSH as follows:

Username: admin password: C1sco123!
Modulus bits 1024
All VTY lines should accept SSH connections only
Connections should require the previously configured username and password.
IP domain name: acad.pt

S-3(config)#ip domain-name acad.pt
S-3(config)#crypto key generate rsa
How many bits in the modulus [512]: 1024

S-3(config)#username admin privilege 15 secret C1sco123!
S-3(config)#enable secret C1sco123!
S-3(config)#line vty 0 15
S-3(config-line)#transport input ssh
S-3(config-line)#login local
S-3(config-line)#exit
S-3(config)#ip ssh version 2

Part 3: VLAN Configuration

Step 1: Configure VLANs according to the VLAN table.

Use the VLAN Table to create and name the VLANs on the appropriate switches.

Part 4: EtherChannel and Trunking Configuration

EtherChannel Port Assignments Table

Channel Group	Devices in Groups	Ports in Group
1	MULTI-1	G1/0/1, G1/0/2
1	S-1	G0/1, G0/2
2	MULTI-1	G1/0/3, G1/0/4
2	S-2	G0/1, G0/2
3	S-1	F0/5, F0/6
3	S-2	F0/5, F0/6

Step 1: Configure EtherChannels

Create EtherChannels according to the EtherChannel Port Assignments Table. Use the Cisco LACP protocol. Both sides of the channel should attempt to negotiate the link protocol.

MULTI-1

MULTI-1(config)#interface range g1/0/1-2
MULTI-1(config-if-range)#channel-group 1 mode active
MULTI-1(config-if-range)#exit
MULTI-1(config)#
MULTI-1(config)#interface range g1/0/3-4
MULTI-1(config-if-range)#channel-group 2 mode active
MULTI-1(config-if-range)#exit

S-1

S-1(config)#interface range g0/1-2
S-1(config-if-range)#channel-group 1 mode active
S-1(config-if-range)#exit
S-1(config)#
S-1(config)#interface range f0/5-6
S-1(config-if-range)#channel-group 3 mode active
S-1(config-if-range)#exit

S-2

S-2(config)#interface range g0/1-2
S-2(config-if-range)#channel-group 2 mode active
S-2(config-if-range)#exit
S-2(config)#
S-2(config)#interface range f0/5-6
S-2(config-if-range)#channel-group 3 mode active
S-2(config-if-range)#exit

Step 2: Configure Trunking on the EtherChannels

a. Configure the port channel interfaces as static trunks. Disable DTP negotiation on all trunks.
b. Troubleshoot any issues that prevent the formation of the EtherChannels.

MULTI-1

MULTI-1(config)#interface port-channel 1
MULTI-1(config-if)#switchport mode trunk
MULTI-1(config-if)#switchport trunk allowed vlan 10,20,30
MULTI-1(config-if)#exit
MULTI-1(config)#
MULTI-1(config)#interface port-channel 2
MULTI-1(config-if)#switchport mode trunk
MULTI-1(config-if)#switchport trunk allowed vlan 10,20,30
MULTI-1(config-if)#exit

S-1

S-1(config)#interface port-channel 1
S-1(config-if)#switchport mode trunk 
S-1(config-if)#switchport nonegotiate
S-1(config-if)#exit
S-1(config)#
S-1(config)#interface port-channel 3
S-1(config-if)#switchport mode trunk 

S-1(config-if)#switchport nonegotiate
S-1(config-if)#exit

S-2

S-2(config)#interface port-channel 2
S-2(config-if)#switchport mode trunk 
S-2(config-if)#switchport nonegotiate
S-2(config-if)#exit
S-2(config)#
S-2(config)#interface port-channel 3
S-2(config-if)#switchport mode trunk 

S-2(config-if)#switchport nonegotiate
S-2(config-if)#exit

Note: Packet Tracer requires configuration of trunking and DTP mode on both portchannel interfaces and the component physical interfaces.

Step 3: Configure a static trunk uplink

a. On the S-3 switch, configure the port that is connected to R-1 G0/0/0 as a static trunk.
b. Configure the NetAdmin VLAN as the native VLAN.
c. Disable DTP on the port.

S-3

S-3(config)#interface g0/1
S-3(config-if)#switchport mode trunk
S-3(config-if)#switchport nonegotiate
S-3(config-if)#switchport trunk native vlan 99
S-3(config-if)#switchport trunk allowed vlan 40,50,60,99
S-3(config-if)#exit

Part 5: Configure Inter-VLAN Routing

Step 1: Configure inter-VLAN routing on the Layer 3 switch.

a. Configure Inter-VLAN routing on the MULTI-1 Layer 3 switch for all VLANs in the VLAN Table that are configured on MULTI-1.
b. Configure the switchport on MULTI-1 that is connected to R-1 with an IP address as shown in the Addressing Table.

MULTI-1

MULTI-1(config)#ip routing
MULTI-1(config)#interface g1/1/1
MULTI-1(config-if)#no switchport
MULTI-1(config-if)#ip address 172.31.0.2 255.255.255.0

Step 2: Configure router-on-a-stick inter-VLAN routing on a router.

a. Configure inter-VLAN routing on R-1 for all the VLANs that are configured on the S-3 switch. Use the information in the Addressing Table.
b. Be sure to configure descriptions of all interfaces.

R-1

R-1(config)#interface g0/0/1
R-1(config-if)#no shutdown 
R-1(config)#interface g0/0/1.40
R-1(config-subif)#description "Gateway for VLAN40"
R-1(config-subif)#encapsulation dot1q 40
R-1(config-subif)#ip address 172.31.40.1 255.255.255.0
R-1(config-subif)#exit
R-1(config)#interface g0/0/1.50
R-1(config-subif)#description "Gateway for VLAN50"
R-1(config-subif)#encapsulation dot1q 50
R-1(config-subif)#ip address 172.31.50.1 255.255.255.0
R-1(config-subif)#exit
R-1(config)#interface g0/0/1.60
R-1(config-subif)#description "Gateway for VLAN60"
R-1(config-subif)#encapsulation dot1q 60
R-1(config-subif)#ip address 172.31.60.1 255.255.255.0
R-1(config-subif)#exit
R-1(config)#interface g0/0/1.99
R-1(config-subif)#description "Gateway for VLAN99"
R-1(config-subif)#encapsulation dot1q 99 native
R-1(config-subif)#ip address 172.31.99.17 255.255.255.240
R-1(config-subif)#exit

Step 3: Configure default gateways on hosts.

a. Configure default gateway addresses on all hosts on the LANs.

Default gateway on Host 1 and Host 4: 172.31.10.1
Default gateway on Host 2 and Host 5: 172.31.20.1
Default gateway on Host 3 and Host 6: 172.31.30.1

Default gateway on Host 7: 172.31.40.1
Default gateway on Host 8: 172.31.50.1
Default gateway on Host 9: 172.31.60.1
Default gateway on Admin Host: 172.31.99.17

b. Verify connectivity between all hosts on both LANs with each other and the Web Server server.
c. Verify that a host can connect to the SVI of switch S-3 over SSH.

Background / Scenario

Instructions

Part 1: Basic Router Configuration

Step 1: Configure router RTR-1 with required settings.

a. Open a command window on router RTR-1 and move to privileged EXEC mode.

b. Copy and paste the following configuration into the RTR-1 router CLI.

ip route 172.31.10.0 255.255.255.0 GigabitEthernet0/0/0

ip route 172.31.20.0 255.255.255.0 GigabitEthernet0/0/0

ip route 172.31.30.0 255.255.255.0 GigabitEthernet0/0/0

ip route 172.31.99.0 255.255.255.240 GigabitEthernet0/0/0

Be sure to press the <Enter> key after the last line to return to privileged EXEC mode prompt.

c. Configure the following settings on the router:

The enable secret password.
A console password
Remote access to the VTY lines.
A banner MOTD message.
The device hostname according to the value in the addressing table.
All clear text passwords should be encrypted.
Interface addressing on G0/0/0 and S0/1/0.
Interface descriptions on G0/0/0 and S0/1/0.

Note: Be sure to make a record of the passwords that you create.

Part 2: Basic Switch Configuration

Step 1: Configure Remote Management Addressing

a. Configure SVI 99 on switch SW-3 with IP addressing according to the Addressing Table.
b. The SW-3 switch SVI should be reachable from other networks.

SW-3(config)#interface vlan 99
SW-3(config-if)#ip address 172.31.99.18 255.255.255.240
SW-3(config-if)#no shutdown
SW-3(config-if)#exit
SW-3(config)#
SW-3(config)#ip default-gateway 172.31.99.17

Step 2: Configure Secure Remote Access

On switch SW-3, configure SSH as follows:

Username: admin password: C1sco123!
Modulus bits 1024
All VTY lines should accept SSH connections only
Connections should require the previously configured username and password.
IP domain name: acad.pt

SW-3(config)#ip domain-name acad.pt
SW-3(config)#crypto key generate rsa
How many bits in the modulus [512]: 1024

SW-3(config)#username admin privilege 15 secret C1sco123!
SW-3(config)#enable secret C1sco123!
SW-3(config)#line vty 0 15
SW-3(config-line)#transport input ssh
SW-3(config-line)#login local
SW-3(config-line)#exit
SW-3(config)#ip ssh version 2

Part 3: VLAN Configuration

Step 1: Configure VLANs according to the VLAN table.

Use the VLAN Table to create and name the VLANs on the appropriate switches.

Part 4: EtherChannel and Trunking Configuration

EtherChannel Port Assignments Table

Channel Group	Devices in Groups	Ports in Group
1	MSW-1	G1/0/1, G1/0/2
1	SW-1	G0/1, G0/2
2	MSW-1	G1/0/3, G1/0/4
2	SW-2	G0/1, G0/2
3	SW-1	F0/5, F0/6
3	SW-2	F0/5, F0/6

Step 1: Configure EtherChannels

Create EtherChannels according to the EtherChannel Port Assignments Table. Use the Cisco LACP protocol. Both sides of the channel should attempt to negotiate the link protocol.

MSW-1

MSW-1(config)#interface range g1/0/1-2
MSW-1(config-if-range)#channel-group 1 mode active
MSW-1(config-if-range)#exit
MSW-1(config)#
MSW-1(config)#interface range g1/0/3-4
MSW-1(config-if-range)#channel-group 2 mode active
MSW-1(config-if-range)#exit

SW-1

SW-1(config)#interface range g0/1-2
SW-1(config-if-range)#channel-group 1 mode active
SW-1(config-if-range)#exit
SW-1(config)#
SW-1(config)#interface range f0/5-6
SW-1(config-if-range)#channel-group 3 mode active
SW-1(config-if-range)#exit

SW-2

SW-2(config)#interface range g0/1-2
SW-2(config-if-range)#channel-group 2 mode active
SW-2(config-if-range)#exit
SW-2(config)#
SW-2(config)#interface range f0/5-6
SW-2(config-if-range)#channel-group 3 mode active
SW-2(config-if-range)#exit

Step 2: Configure Trunking on the EtherChannels

a. Configure the port channel interfaces as static trunks. Disable DTP negotiation on all trunks.
b. Troubleshoot any issues that prevent the formation of the EtherChannels.

MSW-1

MSW-1(config)#interface port-channel 1
MSW-1(config-if)#switchport mode trunk
MSW-1(config-if)#switchport trunk allowed vlan 10,20,30
MSW-1(config-if)#exit
MSW-1(config)#
MSW-1(config)#interface port-channel 2
MSW-1(config-if)#switchport mode trunk
MSW-1(config-if)#switchport trunk allowed vlan 10,20,30
MSW-1(config-if)#exit

SW-1

SW-1(config)#interface port-channel 1
SW-1(config-if)#switchport mode trunk 
SW-1(config-if)#switchport nonegotiate
SW-1(config-if)#exit
SW-1(config)#
SW-1(config)#interface port-channel 3
SW-1(config-if)#switchport mode trunk 

SW-1(config-if)#switchport nonegotiate
SW-1(config-if)#exit

SW-2

SW-2(config)#interface port-channel 2
SW-2(config-if)#switchport mode trunk 
SW-2(config-if)#switchport nonegotiate
SW-2(config-if)#exit
SW-2(config)#
SW-2(config)#interface port-channel 3
SW-2(config-if)#switchport mode trunk 

SW-2(config-if)#switchport nonegotiate
SW-2(config-if)#exit

Note: Packet Tracer requires configuration of trunking and DTP mode on both portchannel interfaces and the component physical interfaces.

Step 3: Configure a static trunk uplink

a. On the SW-3 switch, configure the port that is connected to RTR-1 G0/0/0 as a static trunk.
b. Configure the Management VLAN as the native VLAN.
c. Disable DTP on the port.

SW-3

SW-3(config)#interface g0/1
SW-3(config-if)#switchport mode trunk
SW-3(config-if)#switchport nonegotiate
SW-3(config-if)#switchport trunk native vlan 99
SW-3(config-if)#switchport trunk allowed vlan 40,50,60,99
SW-3(config-if)#exit

Part 5: Configure Inter-VLAN Routing

Step 1: Configure inter-VLAN routing on the Layer 3 switch.

MSW-1

MSW-1(config)#ip routing
MSW-1(config)#interface g1/1/1
MSW-1(config-if)#no switchport
MSW-1(config-if)#ip address 172.31.0.2 255.255.255.0

Step 2: Configure router-on-a-stick inter-VLAN routing on a router.

a. Configure inter-VLAN routing on RTR-1 for all the VLANs that are configured on the SW-3 switch. Use the information in the Addressing Table.
b. Be sure to configure descriptions of all interfaces.

RTR-1

RTR-1(config)#interface g0/0/1
RTR-1(config-if)#no shutdown 
RTR-1(config)#interface g0/0/1.40
RTR-1(config-subif)#description "Gateway for VLAN40"
RTR-1(config-subif)#encapsulation dot1q 40
RTR-1(config-subif)#ip address 172.31.40.1 255.255.255.0
RTR-1(config-subif)#exit
RTR-1(config)#interface g0/0/1.50
RTR-1(config-subif)#description "Gateway for VLAN50"
RTR-1(config-subif)#encapsulation dot1q 50
RTR-1(config-subif)#ip address 172.31.50.1 255.255.255.0
RTR-1(config-subif)#exit
RTR-1(config)#interface g0/0/1.60
RTR-1(config-subif)#description "Gateway for VLAN60"
RTR-1(config-subif)#encapsulation dot1q 60
RTR-1(config-subif)#ip address 172.31.60.1 255.255.255.0
RTR-1(config-subif)#exit
RTR-1(config)#interface g0/0/1.99
RTR-1(config-subif)#description "Gateway for VLAN99"
RTR-1(config-subif)#encapsulation dot1q 99 native
RTR-1(config-subif)#ip address 172.31.99.17 255.255.255.240
RTR-1(config-subif)#exit

Step 3: Configure default gateways on hosts.

a. Configure default gateway addresses on all hosts on the LANs.

Default gateway on PC1 and PC4: 172.31.10.1
Default gateway on PC2 and PC5: 172.31.20.1
Default gateway on PC3 and PC6: 172.31.30.1

Default gateway on PC7: 172.31.40.1
Default gateway on PC8: 172.31.50.1
Default gateway on PC9: 172.31.60.1
Default gateway on PC99: 172.31.99.17

b. Verify connectivity between all hosts on both LANs with each other and the Internet Server server.
c. Verify that a host can connect to the SVI of switch SW-3 over SSH.

Background / Scenario

Instructions

Part 1: Basic Router Configuration

Step 1: Configure router R-1 with required settings.

a. Open a command window on router R-1 and move to privileged EXEC mode.

b. Copy and paste the following configuration into the R-1 router CLI.

ip route 10.0.10.0 255.255.255.0 GigabitEthernet0/0/0

ip route 10.0.20.0 255.255.255.0 GigabitEthernet0/0/0

ip route 10.0.30.0 255.255.255.0 GigabitEthernet0/0/0

ip route 10.0.99.0 255.255.255.240 GigabitEthernet0/0/0

Be sure to press the <Enter> key after the last line to return to privileged EXEC mode prompt.

c. Configure the following settings on the router:

The enable secret password.
A console password
Remote access to the VTY lines.
A banner MOTD message.
The device hostname according to the value in the addressing table.
All clear text passwords should be encrypted.
Interface addressing on G0/0/0 and S0/1/0.
Interface descriptions on G0/0/0 and S0/1/0.

Router(config)#no ip domain lookup
Router(config)#enable secret class

Router(config)#line console 0
Router(config-line)#password cisco
Router(config-line)#login
Router(config-line)#exit

Router(config)#line vty 0 4
Router(config-line)#password cisco
Router(config-line)#login
Router(config-line)#exit

Router(config)#banner motd #Authorized Access Only!#

Router(config)#hostname R-1

R-1(config)#service password-encryption

R-1(config)#interface g0/0/0
R-1(config-if)#ip address 10.0.0.1 255.255.255.0
R-1(config-if)#no shutdown
R-1(config-if)#description Link to Revenue LAN
R-1(config-if)#exit

R-1(config-if)#no shutdown
R-1(config-if)#description Link to Internet
R-1(config-if)#exit

Note: Be sure to make a record of the passwords that you create.

Part 2: Basic Switch Configuration

Step 1: Configure Remote Management Addressing

a. Configure SVI 99 on switch S-3 with IP addressing according to the Addressing Table.
b. The S-3 switch SVI should be reachable from other networks.

S-3(config)#interface vlan 99
S-3(config-if)#ip address 10.0.99.18 255.255.255.240
S-3(config-if)#no shutdown
S-3(config-if)#exit
S-3(config)#
S-3(config)#ip default-gateway 10.0.99.17

Step 2: Configure Secure Remote Access

On switch S-3, configure SSH as follows:

Username: admin password: C1sco123!
Modulus bits 1024
All VTY lines should accept SSH connections only
Connections should require the previously configured username and password.
IP domain name: acad.pt

S-3(config)#ip domain-name acad.pt
S-3(config)#crypto key generate rsa
How many bits in the modulus [512]: 1024

S-3(config)#username admin privilege 15 secret C1sco123!
S-3(config)#enable secret C1sco123!
S-3(config)#line vty 0 15
S-3(config-line)#transport input ssh
S-3(config-line)#login local
S-3(config-line)#exit
S-3(config)#ip ssh version 2

Part 3: VLAN Configuration

Step 1: Configure VLANs according to the VLAN table.

Use the VLAN Table to create and name the VLANs on the appropriate switches.

Part 4: EtherChannel and Trunking Configuration

EtherChannel Port Assignments Table

Channel Group	Devices in Groups	Ports in Group
1	MULTI-1	G1/0/1, G1/0/2
1	S-1	G0/1, G0/2
2	MULTI-1	G1/0/3, G1/0/4
2	S-2	G0/1, G0/2
3	S-1	F0/5, F0/6
3	S-2	F0/5, F0/6

Step 1: Configure EtherChannels

Create EtherChannels according to the EtherChannel Port Assignments Table. Use the Cisco LACP protocol. Both sides of the channel should attempt to negotiate the link protocol.

MULTI-1

MULTI-1(config)#interface range g1/0/1-2
MULTI-1(config-if-range)#channel-group 1 mode active
MULTI-1(config-if-range)#exit
MULTI-1(config)#
MULTI-1(config)#interface range g1/0/3-4
MULTI-1(config-if-range)#channel-group 2 mode active
MULTI-1(config-if-range)#exit

S-1

S-1(config)#interface range g0/1-2
S-1(config-if-range)#channel-group 1 mode active
S-1(config-if-range)#exit
S-1(config)#
S-1(config)#interface range f0/5-6
S-1(config-if-range)#channel-group 3 mode active
S-1(config-if-range)#exit

S-2

S-2(config)#interface range g0/1-2
S-2(config-if-range)#channel-group 2 mode active
S-2(config-if-range)#exit
S-2(config)#
S-2(config)#interface range f0/5-6
S-2(config-if-range)#channel-group 3 mode active
S-2(config-if-range)#exit

Step 2: Configure Trunking on the EtherChannels

a. Configure the port channel interfaces as static trunks. Disable DTP negotiation on all trunks.
b. Troubleshoot any issues that prevent the formation of the EtherChannels.

MULTI-1

MULTI-1(config)#interface port-channel 1
MULTI-1(config-if)#switchport mode trunk
MULTI-1(config-if)#switchport trunk allowed vlan 10,20,30
MULTI-1(config-if)#exit
MULTI-1(config)#
MULTI-1(config)#interface port-channel 2
MULTI-1(config-if)#switchport mode trunk
MULTI-1(config-if)#switchport trunk allowed vlan 10,20,30
MULTI-1(config-if)#exit

S-1

S-1(config)#interface port-channel 1
S-1(config-if)#switchport mode trunk 
S-1(config-if)#switchport nonegotiate
S-1(config-if)#exit
S-1(config)#
S-1(config)#interface port-channel 3
S-1(config-if)#switchport mode trunk 

S-1(config-if)#switchport nonegotiate
S-1(config-if)#exit

S-2

S-2(config)#interface port-channel 2
S-2(config-if)#switchport mode trunk 
S-2(config-if)#switchport nonegotiate
S-2(config-if)#exit
S-2(config)#
S-2(config)#interface port-channel 3
S-2(config-if)#switchport mode trunk 

S-2(config-if)#switchport nonegotiate
S-2(config-if)#exit

Note: Packet Tracer requires configuration of trunking and DTP mode on both portchannel interfaces and the component physical interfaces.

Step 3: Configure a static trunk uplink

a. On the S-3 switch, configure the port that is connected to R-1 G0/0/0 as a static trunk.
b. Configure the ADMIN VLAN as the native VLAN.
c. Disable DTP on the port.

S-3

S-3(config)#interface g0/1
S-3(config-if)#switchport mode trunk
S-3(config-if)#switchport nonegotiate
S-3(config-if)#switchport trunk native vlan 99
S-3(config-if)#switchport trunk allowed vlan 40,50,60,99
S-3(config-if)#exit

Part 5: Configure Inter-VLAN Routing

Step 1: Configure inter-VLAN routing on the Layer 3 switch.

MULTI-1

MULTI-1(config)#ip routing
MULTI-1(config)#interface g1/1/1
MULTI-1(config-if)#no switchport
MULTI-1(config-if)#ip address 10.0.0.2 255.255.255.0

Step 2: Configure router-on-a-stick inter-VLAN routing on a router.

a. Configure inter-VLAN routing on R-1 for all the VLANs that are configured on the S-3 switch. Use the information in the Addressing Table.
b. Be sure to configure descriptions of all interfaces.

R-1

R-1(config)#interface g0/0/1
R-1(config-if)#no shutdown 
R-1(config)#interface g0/0/1.40
R-1(config-subif)#description "Gateway for VLAN40"
R-1(config-subif)#encapsulation dot1q 40
R-1(config-subif)#ip address 10.0.40.1 255.255.255.0
R-1(config-subif)#exit
R-1(config)#interface g0/0/1.50
R-1(config-subif)#description "Gateway for VLAN50"
R-1(config-subif)#encapsulation dot1q 50
R-1(config-subif)#ip address 10.0.50.1 255.255.255.0
R-1(config-subif)#exit
R-1(config)#interface g0/0/1.60
R-1(config-subif)#description "Gateway for VLAN60"
R-1(config-subif)#encapsulation dot1q 60
R-1(config-subif)#ip address 10.0.60.1 255.255.255.0
R-1(config-subif)#exit
R-1(config)#interface g0/0/1.99
R-1(config-subif)#description "Gateway for VLAN99"
R-1(config-subif)#encapsulation dot1q 99 native
R-1(config-subif)#ip address 10.0.99.17 255.255.255.240
R-1(config-subif)#exit

Step 3: Configure default gateways on hosts.

a. Configure default gateway addresses on all hosts on the LANs.

Default gateway on Host 1 and Host 4: 10.0.10.1
Default gateway on Host 2 and Host 5: 10.0.20.1
Default gateway on Host 3 and Host 6: 10.0.30.1

Default gateway on Host 7: 10.0.40.1
Default gateway on Host 8: 10.0.50.1
Default gateway on Host 9: 10.0.60.1
Default gateway on Admin Host: 10.0.99.17

b. Verify connectivity between all hosts on both LANs with each other and the Web Server server.
c. Verify that a host can connect to the SVI of switch S-3 over SSH.

reloading the layer 3 switch worked for LAN 1, but if you follow this configuration you are going to run into dublicated ip addresses for vlan 30,40,50. on vlan interface make sure you configure them with different IPs then those on the router. I read alot about encap dot1q in the comments when making the trunks, that is not necessary. if you use command show inter trunk, you will see that they are encapped when following this config.

The pkt file (that you download for practice) in the Layer 3 Switch configuration, has this configuration:

ip route 0.0.0.0 0.0.0.0 192.168.0.1

You need to remove this static route and put another one related to the ip address of the router interface G0/0/0.
For example, in the ID211, you need to configure this:
no ip route 0.0.0.0 0.0.0.0 192.168.0.1
ip route 0.0.0.0 0.0.0.0 172.31.0.1

Buonasera, ho provato il codice mediante il packet tracer che ha inserito nel download.
Volevo sapere una informazione: alla fine dell’esercizio i punti/triangoli devono essere tutti verdi oppure devono rimanere due punti gialli a sinistra (channel group-3) sull’interfaccia F0/5-6? Io ho tutti i triangoli verdi tranne due punti gialli sulle interfacce F0/5-6 (sul channel group – 3 — parte destra sia sotto che sopra). Inoltre, gli indirizzi ip dei pc non corrispondono con quelli della tabella. Se li modifico, comunque il ping riesco ad eseguirlo. Devono essere modificati gli indirizzi ipv4 dall’ip configuration? Grazie.

I don’t know if this impacts scoring or not, but for pings to work at the end I had to add a default route for L3-SW1 to point to the Edge Router.

Had type 2 test. got 100%! Couldn’t ping the server except from Host99, make sure you add “switchport trunk encapsulation dot1q” before “switchport mode trunk” on L3-SW1 or MSw-A for port channels!

Question to Step 2: Configure Trunking on the EtherChannels.I thought you had to use the same trunk configuration on both sides? If that is correct, then I need to configure nonegation on the L3 switch? Is there any need to configure allowed vlans?

Kratos

3 years ago

when i configured interface ranges on the switches, they were down except for the firsdt one in the range. and when i tried to configure static trunking -i think on L3 switch- it gave an errorm even though i issued the “nonegotiate” command. I think there’s a bug from their side.

You need to add default static routing on Multi-1.

Under multi switch at:
interface range g1/0/1-2
channel-group 1 mode active
exit
interface port-channel 1
switchport mode trunk
switchport trunk allowed vlan 10,20,30
exit
…and at:
interface port-channel 2
switchport mode trunk
switchport trunk allowed vlan 10,20,30

Specifically at sw mode trunk in both cases, I got an error saying “an interface whose trunk encapsulation is “auto” can not be configured to “trunk” mode. If you receive this as well, skip switchport mode trunk and go on to sw trunk allowed…
