Route Redistribution Topology in IPv6

This illustration depicts an example topology of route redistribution in IPv6. This topology is referenced throughout this guide.

In this topology, P15, P3, P6, and P8 represent ports on the SEFOS switches. Switch 1 and switch 2 are NEM switches, and switch 3 is a TOR switch. The following table lists the IPv4 and IPv6 addresses of all the interfaces in both switches and the hosts.
