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
multicast "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, 6514 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.
