Abstract:
The RFCs providing multicast support for BGP/MPLS IP VPNs allow
customer multicast data to be travel across a service provider's
backbone network through a set multicast tunnels. These tunnels are
advertised by BGP in a BGP attribute known as the "Provider Multicast
Service Interface (PMSI) Tunnel Attribute". Encodings have been
defined that allow the PMSI Tunnel Attribute to specify bidirectional
(multipoint-to-multipoint) multicast distribution trees. However,
the prior RFCs do not provide all the necessary details for using
bidirectional tunnels to support multicast VPNs. These details are
provided in the current document. This document also specifies the
procedures for assigning customer multicast flows to specific
bidirectional tunnels in the provider backbone.
