Good evening friends, today we will see how to enable IPv6 on a cisco router with cisco ios. To know what is IPv6, go here. Enabling IPv6 routing on a cisco router is pretty easy and involves only a few commands.
First of all, we have to enable the router to pass IPv6 traffic. In global configuration mode of the router, type command “ipv6 unicast-routing”. Then go to the specific interface on which you want to configure IPv6 addressing by typing command “interface <type> <number>” as shown below. Type command “ipv6 enable”.
Now let’s check whether IPv6 is enabled or not on our specified interface. Go back to Privileged Exec Mode and type command “show ipv6 interface ethernet1/0″. To know about different modes on Cisco IOS, go here. Now when we type the above command, we can see that our device has been assigned a IPv6 address as shown below.
