            Global Table Multicast with BGP-MVPN Procedures
           draft-zzhang-l3vpn-mvpn-global-table-mcast-00.txt

Abstract

   This document describes a way to implement Global Table Multicast,
   aka Internet Multicast, using BGP encodings and procedures for MVPN
   as specified in [RFC6514].

   No protocol modification/extension is required.  This is purely for
   informational and clarifying purposes only.

Internet-Draft    Global Table Multicast with BGP-MVPN         July 2013

1.  Introduction

   [RFC6513] and [RFC6514] specify procedures and encodings to implement
   Multicast for L3VPNs (MVPN).  [RFC6513] specifies general concepts
   and procedures that apply to PIM-based and/or BGP-based C-Multicast
   State Signaling (referred to PIM-MVPN and BGP-MVPN respectively), and
   [RFC6514] specifies BGP procedures and encodings used by both PIM-
   MVPN and BGP-MVPN.

   While [RFC6513] and [RFC6514] assume the context of VPN, they can be
   used to implement Global (vs. VRF) Table Multicast as well, without
   any protocol modification/extension, even though the RFCs do not
   explicitly mention it.

   Consider a provider network in which the "core" part of it uses MPLS
   P2MP LSPs or Ingress Replication over either P2P LSPs (with RSVP-TE)
   or MP2P LSPs (with LDP) instead of PIM to carry multicast traffic
   among the MPLS Border Routers (MBRs) of the core.  Those MBRs run PIM
   on interfaces connected to other routers outside the core.

   This document describes how Global Table Multicast can be implemented
   using BGP-MVPN procedures.  We start with a simple reference scenario
   below, and also discuss one slightly different scenario and another
   special one.
