The number used in the ipv6 router eigrp asn command is the ASN (autonomous system number) and not the process ID as used by OSPFv3. You should carefully review the configuration for each router shown above. The only difference is that there are no areas in EIGRPv6. The topology consists of four routers and some of you may have noticed that the topology is the same that we used for multi-area OSPFv3 configuration earlier in the chapter, and also uses identical IPv6 addressing scheme. We will use the topology consisting of four routers as shown in Figure 13-9 for this example. Enable EIGRPv6 on interfaces using the ipv6 eigrp asn command in interface configuration mode.

Assign an EIGRPv6 router ID using the eigrp router-id router-id command in router configuration mode.Create an EIGRPv6 process using ipv6 router eigrp asn command.Enable IPv6 routing using ipv6 unicast-routing command.EIGRPv6 also has the same successor and feasible successor (FS) concepts.Д®IGRPv6 involves the following configuration steps: EIGRPv6 then exchange messages allowing the routers to discover neighbors, form neighbor relationships, and finally advertise subnets along with the metric components for each route. EIGRPv6 has to be enabled on all routers in the network just like EIGRPv4. The IPv4 and IPv6 versions of EIGRP are even closer to each other than the two corresponding versions of OSPF. Cisco designed the new EIGRPv6 (EIGRP for IPv6) to be almost identical to EIGRPv4 (EIGRP for IPv4).
