IPv6 MBGP overview

IETF defined Multiprotocol BGP (MP-BGP) to carry routing information for multiple network-layer
protocols.
For an IPv6 network, the topology for IPv6 multicast might be different from that for IPv6 unicast. To
distinguish them, the MP-BGP enables BGP to carry the IPv6 unicast Network Layer Reachability
Information (NLRI) and IPv6 multicast NLRI separately, and the multicast NLRI performs reverse path
forwarding (RPF) exclusively. In this way, route selection for a destination through the IPv6 unicast
routing table and through the IPv6 multicast routing table have different results, ensuring consistent
unicast forwarding and normal multicast between domains.
MP-BGP is defined in RFC 2858 (Multiprotocol Extensions for BGP-4). The application of MP-BGP on
IPv6 multicast is called IPv6 Multicast BGP (IPv6 MBGP).
