Cisco IPv6 Training IPv6 EIGRP Differences

How is EIGRPv6 different from EIGRPv4?

By Charles Ross CCNP #CSCO10444244

In a nutshell, the overall operation and features of EIGRPv6 are still the same as they are in EIGRPv4. But, EIGRPv6 does differ from EIGRPv4 in the following ways:

• EIGRPv6 is configured (enabled) directly on Cisco router’s interfaces; this means EIGRPv6 can be configured (enabled) on a router’s interface, without having to configure (assign) a Global IPv6 address on the interface and without using the “network” command while the router is in router configuration mode.

• Also, when configuring (enabling) EIGRPv6 on a Cisco router, the EIGRP routing process must be configured (assigned) with a “router-id” (by using the router configuration command “router-id”); if a “router-id” is not configured (assigned) the EIGRPv6 routing process will not start.

• The EIGRPv6 routing process also uses a “shutdown” feature; meaning an EIGRPv6 routing process will not start until the routing process has been placed into “no shutdown” mode. (by, typing the “no shutdown” command while the router is in router configuration mode)

• Also, on Passive Interfaces; EIGRPv6 is not required to be configured.

• Lastly, EIGRPv6 use the router configuration command “distribute-list prefix-list” to perform route filtering; and when configuring route filtering the “route-map” command is not supported.
