Configure Router Interfaces

Packet Tracer - Configure Router Interfaces

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.

Part 1: Configure IPv4 Addressing and Verify Connectivity

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

From the global config prompt, start with the first interface under R1 which is the G0/0 interface.

R1(config)#interface g0/0

From here you can set the IP address assigned to this interface and enable it:

R1(config-if)# ip add 172.16.20.1 255.255.255.128

R1(config-if)# no shut

To switch to a different interface, all you have to do is use the interface command and you can set the IP addresses of the other interfaces:

R1(config-if)#int g0/1

R1(config-if)#ip add 172.16.20.129 255.255.255.128

R1(config-if)#no shut

The serial connection was already established, but this would be the command to set the IP address:

R1(config-if)#int s0/0/0

R1(config-if)#ip add 209.165.200.225 255.255.255.252

To configure the IP addresses of the PCs, click on the individual PC, go to the desktop tab, and set the IP address, subnet address, and default gateway according to the chart.

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.

From the global config prompt, start with the first interface under R2 which is the G0/0 interface and do the same as in Part 1 but with the IPv6 command and addresses.

R2(config)#interface g0/0

R2(config-if)# ipv6 add 2001:db8:c0de:12::1/64

R2(config-if)# no shut

R2(config-if)#interface g0/1

R2(config-if)# ipv6 add 2001:db8:c0de:13::1/64

R2(config-if)# no shut

The serial interface is already set up but if this would be the command:

R2(config-if)#interface s/0/0/1

R2(config-if)# ipv6 add 2001:db8:c0de:11::1/64

R2(config-if)# no shut

To configure the IP addresses of the PCs, click on the individual PC, go to the desktop tab, and set the IPv6 address, subnet prefix, and gateway address according to the chart.

Step 2: Verify connectivity.

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