CCNA 200–301

Lab Objective:

The objective of this lab exercise is for you to learn and understand how to configure IPv6 addresses on Cisco routers using address autoconfiguration and EUI-64 addressing.

Lab Purpose:

Configuring IPv6 addressing is one of your most fundamental tasks as a Cisco engineer. In the exam, you may also be asked to configure an IPv6 address using Stateless Address Autoconfiguration (SLACC) as well as EUI-64 addressing.

Simulator

Cisco Packet Tracer

Lab Topology:

Please use the following topology to complete this lab exercise:

Task 1:

Configure the hostnames on routers R1 and R3 as illustrated in the topology.

Task 2:

Configure the IP addresses on the Ethernet interfaces of R1 and R3 as illustrated in the topology. Configure the Loopback interfaces specified in the diagram on R3.

F0/0 on R3 will use SLACC to obtain the address prefix from R1. Loopback0 will use EUI-64 to complete the host portion of the address.

Task 3:

Use the correct show commands to check:

  1. The summary of all configured IP addresses;
  2. The status of the interface (up/down or administratively down); and
  3. The subnet mask applied to the interface.

Task 1:

Router#config t
Router(config)#hostname R1

Router#config t
Router(config)#hostname R3

Task 2:

R1(config)#ipv6 unicast-routing
R1(config)#interface f0/0
R1(config-if)#ipv6 add 2001:abcd:abcd::1/64
R1(config-if)#no shut

R3(config)#ipv6 unicast-routing
R3(config)#interface f0/0
R3(config-if)#ipv6 add autoconfig
R3(config-if)#no shut
R3(config)#interface lo0
R3(config-if)# ipv6 address 2001:aaaa:aaaa:aaaa::/64 eui-64

Task 3:

R3#show ipv6 int f0/0

R3#show ipv6 int lo0
