Abstract:
A set of prior RFCs specify procedures for supporting multicast in
BGP/MPLS IP VPNs. These procedures allow customer multicast data to
travel across a service provider's backbone network through a set of
multicast tunnels. The tunnels are advertised in certain BGP "auto-
discovery" routes, by means of a BGP attribute known as the "Provider
Multicast Service Interface (PMSI) Tunnel attribute". Encodings have
been defined that allow the PMSI Tunnel attribute to identify
bidirectional (multipoint-to-multipoint) multicast distribution
trees. However, the prior RFCs do not provide all the necessary
procedures for using bidirectional tunnels to support multicast VPNs.
This document updates RFCs 6513 and 6625 by specifying those
procedures. In particular, it specifies the procedures for assigning
customer multicast flows (unidirectional or bidirectional) to
specific bidirectional tunnels in the provider backbone, for
advertising such assignments, and for determining which flows have
been assigned to which tunnels.
