Multiprotocol BGP

Multiprotocol BGP (MBGP), which is also known as BGP4+, is an enhanced BGP that supports more than just IPv4 unicast routes. In this release, MBGP supports:

MBGP support for separate unicast and multicast routing tables allows BGP to have non-congruent topologies for unicast and multicast networks. The BGP multicast address-family routes are used by multicast protocols such as Protocol Independent Multicast (PIM) to build data distribution trees.
