Now, some of you maybe wondering, why did he write an article on how to enable EIGRPv6 on a Cisco Router, when I already know how to do that?

Well, to answer your question, enabling EIGRP on a router that is running on an IPv6 network, is slightly different from enabling EIGRP on a router that is running on an IPv4 network.

Meaning, a router that is running on an IPv6 network, had EIGRP (EIGRPv6) enabled per interface, instead of globally like a router running on an IPv4 network would. So, in other words, when enabling EIGRPv6 on a Cisco router, you don’t need to use the “network” command when the router is in Router Configuration Mode.

Instead you’ll need to perform the following steps:

1. Router>enable
2. Router#configure terminal
3. Router(config)#ipv6 unicast-routing
4. Router(config)#interface type number
5. Router(config-if)#ipv6 enable
6. Router(config-if)#ipv6 eigrp as-number
7. Router(config-if)#no shutdown
8. Router(config-if)#ipv6 router eigrp as-number
9. Router(config-router)#router-id {ip-address | ipv6-address}
10. Router(config-router)#no shutdown
11. Router(config-router)#exit
12. Router(config)#exit
13. Router#copy run start

Steps Explained:

Step #1

1. Router>enable

Puts router into Privileged EXEC mode.

Step #2

2. Router#configure terminal

Puts router into Global configuration mode.

Step #3

3. Router(config)#ipv6 unicast-routing

Configures the router to route IPv6 packets

Step #4

4. Router(config)#interface fastethernet 0/0

Specifies the fastethernet 0/0 interface on which EIGRPv6 is to be configured.

Step #5

5. Router(config-if)#ipv6 enable

Enables IPv6 processing on the fastethernet 0/0 interface.

Step #6

6. Router(config-if)#ipv6 eigrp 1

Enables the EIGRP for IPv6 process on the fastethernet 0/0 interface.

Step #7

7. Router(config-if)#no shutdown

Starts the EIGRP for IPv6 protocol (process) without changing any per-interface configuration.

Step #8

8. Router(config-if)#ipv6 router eigrp 1

Puts the router into router configuration mode and creates an EIGRP for IPv6 routing process.

Step #9

9. Router(config-router)#router-id {ip-address | ipv6-address}

Enables the router to use a fixed router ID. (Remember each router Id must be unique)

Step #10

10. Router(config-router)#no shutdown

Put the EIGRPv6 routing process in “no shutdown” mode in order to start the EIGRPv6 process.

Step #11

11. Router(config-router)#exit

Returns the router to Global configuration mode

Step #12

12. Router(config)#exit

Returns the router to Privileged EXEC mode.

Step #13

13. Router#copy run start

Saves the contents of the running-config to local Non -Volatile Random Access Memory (NVRAM).
