Objectives

  • Part 1: Configure IPv4 Addressing and Verify Connectivity
  • Part 2: Configure IPv6 Addressing and Verify Connectivity

Background

Routers R1 and R2 each have two LANs. Your task is to configure the appropriate addressing on each device and verify connectivity between the LANs.

Note: The user EXEC password is cisco. The privileged EXEC password is class.

Instructions

Part 1: Configure IPv4 Addressing and Verify Connectivity

Step 1: Assign IPv4 addresses to R1 and LAN devices.

Referring to the Addressing Table, configure IP addressing for R1 LAN interfaces, PC1 and PC2. The serial interface has already configured.

R1>enable
Password: 
R1#configure terminal
R1(config)#interface g0/0
R1(config-if)#ip address 172.16.20.1 255.255.255.128
R1(config-if)#no shutdown

R1(config-if)#interface g0/1
R1(config-if)#ip address 172.16.20.129 255.255.255.128
R1(config-if)#no shutdown
R1(config-if)#

Step 2: Verify connectivity.

PC1 and PC2 should be able to ping each other and the Dual Stack Server.

Part 2: Configure IPv6 Addressing and Verify Connectivity

Step 1: Assign IPv6 addresses to R2 and LAN devices.

Referring to the Addressing Table, configure IP addressing for R2 LAN interfacesPC3 and PC4. The serial interface is already configured.

R2>enable
Password: 
R2#configure terminal

R2(config)#interface g0/0
R2(config-if)#ipv6 address 2001:db8:c0de:12::1/64
R2(config-if)#no shutdown
R2(config-if)#exit

R2(config)#interface g0/1
R2(config-if)#ipv6 address 2001:db8:c0de:13::1/64
R2(config-if)#no shutdown

Step 2: Verify connectivity.

PC3 and PC4 should be able to ping each other and the Dual Stack Server.
