  • Set weight to 100 on R1 to make the route a best path.
  • Create a route map that changes the next hop to a valid IPv6 address and attach it to the IPv6 AF on R1.
  • Create a route map that changes the next hop to a valid IPv6 address and attach it to the neighbor statement on R2.
  • Set local preference to 200 on R2 to make the route a best path.

Explanation: The show bgp ipv6 unicast command can be used to verify the IPv6 unicast routes that have been learned from all neighbors. The route 2001:db8:2::/64 is the route that was learned from the neighbor at 2.2.2.2. Because the next hop is not reachable, route 2001:db8:2::/64 is not installed in the routing table. The address of ::FFFF:2.2.2.2 is a dynamically generated next hop that was created to replace the original next hop of 2.2.2.2. This occurs because an IPv6 route cannot have an IPv4 next-hop address. To solve this issue, a route map can be created that changes the next hop to a valid IPv6 address and attach it to the neighbor statement. This needs to be done on the router that advertises the route, not on the router receiving the route.
