Lab – Configuring IPv6 on a Cisco IOS router

To get started, we are going to use the following topology:

Fig 3.48 – Lab topology

To configure IPv6 address on a Cisco IOS router, use the following steps:

1. Enable IPv6 routing using the following command:

   R1(config)#ipv6 unicast-routing

2. Enter interface mode for the desired interface:

   R1(config)#interface GigabitEthernet0/0

3. Use the ipv6 address command, followed by the IPv6 address with the network prefix:

   R1(config-if)#ipv6 address 2001:DB8:1:1::1/64

4. (Optional) To manually configure a Link-Local IPv6 address on the interface, use the link-local command after the IPv6 address, as shown here:

   R1(config-if)#ipv6 address FE80::1 link-local

5. Enable the interface using the no shutdown command:

   R1(config-if)#no shutdown

Now that you have learned how to configure IPv6 global and Link-Local addresses, let's take a look at how to verify our configurations using Cisco IOS commands...
