Objectives
- Part 1: Build the Network and Configure Basic Device Settings
- Part 2: Configure and verify two DHCPv4 Servers on R1
- Part 3: Configure and verify a DHCP Relay on R2
Background / Scenario
The Dynamic Host Configuration Protocol (DHCP) is a network protocol that lets network administrators manage and automate the assignment of IP addresses. Without DHCP for IPv4, the administrator must manually assign and configure IP addresses, preferred DNS servers, and default gateways. As the network grows in size, this becomes an administrative problem when devices are moved from one internal network to another.
In this scenario, the company has grown in size, and the network administrators can no longer assign IP addresses to devices manually. Your job is to configure the R1 router to assign IPv4 addresses on two different subnets.
Note: The routers used with CCNA hands-on labs are Cisco 4221 with Cisco IOS XE Release 16.9.4 (universalk9 image). The switches used in the labs are Cisco Catalyst 2960s with Cisco IOS Release 15.2(2) (lanbasek9 image). Other routers, switches, and Cisco IOS versions can be used. Depending on the model and Cisco IOS version, the commands available and the output produced might vary from what is shown in the labs. Refer to the Router Interface Summary Table at the end of the lab for the correct interface identifiers.
Note: Ensure that the routers and switches have been erased and have no startup configurations. If you are unsure contact your instructor.
Instructor Note: Refer to the Instructor Lab Manual for the procedures to initialize and reload devices

Instructions
Part 1: Build the Network and Configure Basic Device Settings
In Part 1, you will set up the network topology and configure basic settings on the PC hosts and switches.
Step 1: Establish an addressing scheme
Subnet the network 192.168.1.0/24 to meet the following requirements:
a. One subnet, “Subnet A”, supporting 58 hosts (the client VLAN at R1).
Subnet A:
192.168.1.0/26 (.1 -.63)
Record the first IP address in the Addressing Table for R1 G0/0/1.100. Record the second IP address in the Address Table for S1 VLAN 200 and enter the associated default gateway.
b. One subnet, “Subnet B”, supporting 28 hosts (the management VLAN at R1).
Subnet B:
192.168.1.64/27 (.65-.95)
Record the first IP address in the Addressing Table for R1 G0/0/1.200. Record the second IP address in the Address Table for S1 VLAN 1 and enter the associated default gateway.
c. One subnet, “Subnet C”, supporting 12 hosts (the client network at R2).
Subnet C:
192.168.1.96/28 (.97-.111)
Record the first IP address in the Addressing Table for R2 G0/0/1.
Step 2: Cable the network as shown in the topology.
Attach the devices as shown in the topology diagram, and cable as necessary.
Step 3: Configure basic settings for each router.
a. Assign a device name to the router.
router(config)# hostname R1
b. Disable DNS lookup to prevent the router from attempting to translate incorrectly entered commands as though they were host names.
R1(config)# no ip domain-lookup
c. Assign class as the privileged EXEC encrypted password.
R1(config)# enable secret class
d. Assign cisco as the console password and enable login.
R1(config)# line console 0 R1(config-line)# password cisco R1(config-line)# login
e. Assign cisco as the VTY password and enable login.
R1(config)# line vty 0 4 R1(config-line)# password cisco R1(config-line)# login
f. Encrypt the plaintext passwords.
R1(config)# service password-encryption
g. Create a banner that warns anyone accessing the device that unauthorized access is prohibited.
R1(config)# banner motd $ Authorized Users Only! $
h. Save the running configuration to the startup configuration file.
R1# copy running-config startup-config
i. Set the clock on the router to today’s time and date.
R1# clock set 15:30:00 27 Aug 2019
Note: Use the question mark (?) to help with the correct sequence of parameters needed to execute this command.
Step 4: Configure Inter-VLAN Routing on R1
a. Activate interface G0/0/1 on the router.
R1(config)# interface g0/0/1 R1(config-if)# no shutdown R1(config-if)# exit
b. Configure sub-interfaces for each VLAN as required by the IP addressing table. All sub-interfaces use 802.1Q encapsulation and are assigned the first usable address from the IP address pool you have calculated. Ensure the sub-interface for the native VLAN does not have an IP address assigned. Include a description for each sub-interface.
R1(config)# interface g0/0/1.100 R1(config-subif)# description Client Network R1(config-subif)# encapsulation dot1q 100 R1(config-subif)# ip address 192.168.1.1 255.255.255.192 R1(config-subif)# interface g0/0/1.200 R1(config-subif)# encapsulation dot1q 200 R1(config-subif)# description Management Network R1(config-subif)# ip address 192.168.1.65 255.255.255.224 R1(config-subif)# interface g0/0/1.1000 R1(config-subif)# encapsulation dot1q 1000 native R1(config-subif)# description Native VLAN
c. Verify the sub-interfaces are operational.
R1# show ip interface brief Interface IP-Address OK? Method Status Protocol GigabitEthernet0/0/0 unassigned YES unset administratively down down GigabitEthernet0/0/1 unassigned YES unset up up Gi0/0/1.100 192.168.1.1 YES manual up up Gi0/0/1.200 192.168.1.65 YES manual up up Gi0/0/1.1000 unassigned YES unset up up
Step 5: Configure G0/0/1 on R2, then G0/0/0 and static routing for both routers
a. Configure G0/0/1 on R2 with the first IP address of Subnet C you calculated earlier.
R2(config)# interface g0/0/1 R2(config-if)# ip address 192.168.1.97 255.255.255.240 R2(config-if)# no shutdown R2(config-if)# exit
b. Configure interface G0/0/0 for each router based on the IP Addressing table above.
R1(config)# interface g0/0/0 R1(config-if)# ip address 10.0.0.1 255.255.255.252 R1(config-if)# no shutdown R2(config)# interface g0/0/0 R2(config-if)# ip address 10.0.0.2 255.255.255.252 R2(config-if)# no shutdown
c. Configure a default route on each router pointed to the IP address of G0/0/0 on the other router.
R1(config)# ip route 0.0.0.0 0.0.0.0 10.0.0.2 R2(config)# ip route 0.0.0.0 0.0.0.0 10.0.0.1
d. Verify static routing is working by pinging R2’s G0/0/1 address from R1.
R1# ping 192.168.1.97
e. Save the running configuration to the startup configuration file.
R1# copy running-config startup-config
Step 6: Configure basic settings for each switch.
a. Assign a device name to the switch.
switch(config)# hostname S1
b. Disable DNS lookup to prevent the router from attempting to translate incorrectly entered commands as though they were host names.
S1(config)# no ip domain-lookup
c. Assign class as the privileged EXEC encrypted password.
S1(config)# enable secret class
d. Assign cisco as the console password and enable login.
S1(config)# line console 0 S1(config-line)# password cisco S1(config-line)# login
e. Assign cisco as the VTY password and enable login.
S1(config)# line vty 0 4 S1(config-line)# password cisco S1(config-line)# login
f. Encrypt the plaintext passwords.
S1(config)# service password-encryption
g. Create a banner that warns anyone accessing the device that unauthorized access is prohibited.
S1(config)# banner motd $ Authorized Users Only! $
h. Save the running configuration to the startup configuration file.
S1(config)# exit S1# copy running-config startup-config
i. Set the clock on the switch to today’s time and date.
S1# clock set 15:30:00 27 Aug 2019
Note: Use the question mark (?) to help with the correct sequence of parameters needed to execute this command.
j. Copy the running configuration to the startup configuration.
Step 7: Create VLANs on S1.
Note: S2 is only configured with basic settings.
a. Create and name the required VLANs on switch 1 from the table above.
S1(config)# vlan 100 S1(config-vlan)# name Clients S1(config-vlan)# vlan 200 S1(config-vlan)# name Management S1(config-vlan)# vlan 999 S1(config-vlan)# name Parking_Lot S1(config-vlan)# vlan 1000 S1(config-vlan)# name Native S1(config-vlan)# exit
b. Configure and activate the management interface on S1 (VLAN 200) using the second IP address from the subnet calculated earlier. Additionally, set the default gateway on S1.
S1(config)# interface vlan 200 S1(config-if)# ip address 192.168.1.66 255.255.255.224 S1(config-if)# no shutdown S1(config-if)# exit S1(config)# ip default-gateway 192.168.1.65
c. Configure and activate the management interface on S2 (VLAN 1) using the second IP address from the subnet calculated earlier. Additionally, set the default gateway on S2
S2(config)# interface vlan 1 S2(config-if)# ip address 192.168.1.98 255.255.255.240 S2(config-if)# no shutdown S2(config-if)# exit S2(config)# ip default-gateway 192.168.1.97
d. Assign all unused ports on S1 to the Parking_Lot VLAN, configure them for static access mode, and administratively deactivate them. On S2, administratively deactivate all the unused ports.
Note: The interface range command is helpful to accomplish this task with as few commands as necessary.
S1(config)# interface range f0/1 - 4, f0/7 - 24, g0/1 - 2 S1(config-if-range)# switchport mode access S1(config-if-range)# switchport access vlan 999 S1(config-if-range)# shutdown S1(config-if-range)# exit S2(config)# interface range f0/1 - 4, f0/6 - 17, f0/19 - 24, g0/1 - 2 S2(config-if-range)# switchport mode access S2(config-if-range)# shutdown S2(config-if-range)# exit
Step 8: Assign VLANs to the correct switch interfaces.
a. Assign used ports to the appropriate VLAN (specified in the VLAN table above) and configure them for static access mode.
S1(config)# interface f0/6 S1(config-if)# switchport mode access S1(config-if)# switchport access vlan 100
b. Verify that the VLANs are assigned to the correct interfaces.
S1# show vlan brief

Why is interface F0/5 listed under VLAN 1?
Port 5 is in the default VLAN and has not been configured as an 802.1Q trunk.
Step 9: Manually configure S1’s interface F0/5 as an 802.1Q trunk.
a. Change the switchport mode on the interface to force trunking.
S1(config)# interface f0/5 S1(config-if)# switchport mode trunk
b. As a part of the trunk configuration, set the native VLAN to 1000.
S1(config-if-range)# switchport trunk native vlan 1000
c. As another part of trunk configuration, specify that VLANs 100, 200, and 1000 are allowed to cross the trunk.
S1(config-if-range)# switchport trunk allowed vlan 100,200,1000
d. Save the running configuration to the startup configuration file.
S1(config)# exit S1# copy running-config startup-config
e. Verify trunking status.
S1# show interfaces trunk Port Mode Encapsulation Status Native vlan Fa0/5 on 802.1q trunking 1000 Port Vlans allowed on trunk Fa0/5 100,200,1000 Port Vlans allowed and active in management domain Fa0/5 100,200,1000 Port Vlans in spanning tree forwarding state and not pruned Fa0/5 100,200,1000
At this point, what IP address would the PC’s have if they were connected to the network using DHCP?
They would self-configure with an Automatic Private IP Address (APIPA) address in the 169.254.x.x range.
Part 2: Configure and verify two DHCPv4 Servers on R1
In Part 2, you will configure and verify a DHCPv4 Server on R1. The DHCPv4 server will service two subnets, Subnet A and Subnet C.
Step 1: Configure R1 with DHCPv4 pools for the two supported subnets. Only the DHCP Pool for subnet A is given below
a. Exclude the first five useable addresses from each address pool.
R1(config)# ip dhcp excluded-address 192.168.1.1 192.168.1.5
b. Create the DHCP pool (Use a unique name for each pool).
R1(config)# ip dhcp pool R1_Client_LAN
c. Specify the network that this DHCP server is supporting.
R1(dhcp-config)# network 192.168.1.0 255.255.255.192
d. Configure the domain name as ccna-lab.com
R1(dhcp-config)# domain-name ccna-lab.com
e. Configure the appropriate default gateway for each DHCP pool.
R1(dhcp-config)# default-router 192.168.1.1
f. Configure the lease time for 2 days 12 hours and 30 minutes.
R1(dhcp-config)# lease 2 12 30
The Packet Tracer software doesn’t support all IOS commands and features.
g. Next, configure the second DHCPv4 Pool using the pool name R2_Client_LAN and the calculated network, default-router and use the same domain name and lease time from the previous DHCP pool.
R1(config)# ip dhcp excluded-address 192.168.1.97 192.168.1.101 R1(config)# ip dhcp pool R2_Client_LAN R1(dhcp-config)# network 192.168.1.96 255.255.255.240 R1(dhcp-config)# default-router 192.168.1.97 R1(dhcp-config)# domain-name ccna-lab.com R1(dhcp-config)# lease 2 12 30
Step 2: Save your configuration
Save the running configuration to the startup configuration file.
R1# copy running-config startup-config
Step 3: Verify the DHCPv4 Server configuration
a. Issue the command show ip dhcp pool to examine the pool details.
b. Issue the command show ip dhcp bindings to examine established DHCP address assignments.
c. Issue the command show ip dhcp server statistics to examine DHCP messages.
Step 4: Attempt to acquire an IP address from DHCP on PC-A
a. Open a command prompt on PC-A and issue the command ipconfig /renew.
Packet Tracer: Configure host PC-A to receive their IP addresse from a DHCP server.
b. Once the renewal process is complete, issue the command ipconfig to view the new IP information.
c. Test connectivity by pinging R1’s G0/0/1 interface IP address.
Part 3: Configure and verify a DHCP Relay on R2
In Part 3, you will configure R2 to relay DHCP requests from the local area network on interface G0/0/1 to the DHCP server (R1).
Step 1: Configure R2 as a DHCP relay agent for the LAN on G0/0/1
a. Configure the ip helper-address command on G0/0/1 specifying R1’s G0/0/0 IP address.
R2(config)# interface g0/0/1 R2(config-if)# ip helper-address 10.0.0.1
b. Save your configuration.
R2(config-if)# end R2# wr
Step 2: Attempt to acquire an IP address from DHCP on PC-B
a. Open a command prompt on PC-B and issue the command ipconfig /renew.
b. Once the renewal process is complete, issue the command ipconfig to view the new IP information.
c. Test connectivity by pinging R1’s G0/0/1 interface IP address.
d. Issue the show ip dhcp binding on R1 to verify DHCP bindings.
e. Issue the show ip dhcp server statistics on R1 and R2 to verify DHCP messages.
