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
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 encrypted 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.

SRWE PT Practice Skills Assessment (PTSA) Part 1
A few things to keep in mind while completing this activity:
- Do not use the browser Back button or close or reload any exam windows during the exam.
- Do not close Packet Tracer when you are done. It will close automatically.
- Click the Submit Assessment button in the browser window to submit your work.
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 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
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 RTR-1 RTR-1(config)#service password-encryption RTR-1(config)#interface g0/0/0 RTR-1(config-if)#ip address 172.31.0.1 255.255.255.0 RTR-1(config-if)#no shutdown RTR-1(config-if)#description Link to LAN 1 RTR-1(config-if)#exit RTR-1(config)#interface s0/1/0 RTR-1(config-if)#ip address 209.165.201.2 255.255.255.252 RTR-1(config-if)#no shutdown 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 encrypted 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.

| SW-2 | G0/1, G0/2 | |
| 3 | SW-1 | F0/5, F0/6 |
| 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-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

SRWE PT Practice Skills Assessment (PTSA) Part 1
A few things to keep in mind while completing this activity:
- Do not use the browser Back button or close or reload any exam windows during the exam.
- Do not close Packet Tracer when you are done. It will close automatically.
- Click the Submit Assessment button in the browser window to submit your work.
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 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
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)#interface s0/1/0 R-1(config-if)#ip address 209.165.201.2 255.255.255.252 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 encrypted 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.

| S-2 | G0/1, G0/2 | |
| 3 | S-1 | F0/5, F0/6 |
| 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(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.
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 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.
