MP-BGP for IPv6
Multiprotocol BGP (RFC 2858) involves two new extensions to BGP4 that
allow BGP to carry reachability information for other protocols, such as
IPv6, multicast IPv4, and MPLS. The extensions allow NEXT_HOP to carry
IPv6 addresses and NLRI (network layer reachability information) to an
IPv6 prefix.
Example 8-5 shows the BGP commands as they might be applied.
