What is EIGRPv6? Explained with Examples

By | 9th November 2015

The Enhanced Interior Gateway Routing Protocol (EIGRP) for IPv6 – EIGRPv6.  EIGRP is an enhanced version of the IGRP developed by Cisco.
EIGRP for IPv6 works in the same way as EIGRP IPv4 where they can be configured and managed separately.

EIGRPv6 is still a distant-vector routing protocol with same link-state features, The hello process used in neighbour discovery and the Diffusing Update Algorithm (DUAL) use for loop free and fast convergence is still much present. Like its fellow IPv6 Protocols ( RIPng and OSPFv3), there are similarities in the processing features of IPv4 routing protocols.

EIGRP for IPv6 still possesses the same overall  features and operation as EIGRP for IPv4; only there are a few major differences between them:

•           EIGRP for IPv6 is configured directly on the router interfaces.

•           With EIGRP for IPv6, a router ID is required on each router or the routing process does not start.

•           The EIGRP for IPv6 routing process uses a shutdown feature.

*      EIGRPv6 uses a multicast address of FF02::10 for routing updates and hello packets.

How to configure EIGRPv6.

Unlike its predecessor eigrp IPv4, IPv6 is enabled directly to the interface without the network command. However, you can still use the router configuration mode to enable it and it must be turned on using the shutdown command.

EIGRPv6 Configuration Example:


The 22 is the autonomous system (AS) number. If you look closely, you will notice the prompt changed to(config-rtr) and from here you must use the no shutdown command.

On the interface fa0/0 configuration, same 22 references the AS number that was enabled in the configuration mode.
