            Global Table Multicast with BGP-MVPN Procedures

           draft-zzhang-l3vpn-mvpn-global-table-mcast-01.txt

Abstract

   RFC6513, RFC6514, and other RFCs describe protocols and procedures
   which a Service Provider (SP) may deploy in order offer Multicast
   Virtual Private Network (Multicast VPN or MVPN) service to its
   customers.  Some of these procedures use BGP to distribute VPN-
   specific multicast routing information across a backbone network.
   With a small number of relatively minor modifications, the very same
   BGP procedures can also be used to distribute multicast routing
   information that is not specific to any VPN.  Multicast that is
   outside the context of a VPN is known as "Global Table Multicast", or
   sometimes simply as "Internet multicast".  In this document, we
   describe the modifications that are needed to use the MVPN BGP
   procedures for Global Table Multicast.
