The Multiprotocol Extensions for BGP-4 [MBGP] allow Network Layer Reachability Information to contain prefixes used for multicast forwarding. This document defines extensions to BGP-4 [BGP-4] which can be used to annotate such prefixes with information that can be used by multicast routing protocols when constructing trees.
