Abstract

   When a Service Provider offers BGP/MPLS IP VPN service to its
   customers, RFCs 6513 and 6514 describe protocols and procedures that
   the Service Provider can use in order to carry the customer's IP
   multicast traffic from one customer site to others.  BGP can be used
   to carry customer multicast routing information from one Provider
   Edge (PE) router to another, but it is assumed that PIM is running on
   the interface between a Customer Edge (CE) router and a PE router.
   This document specifies protocols and procedures that, under certain
   conditions, allow customer multicast routing information to carried
   between PE and CE via BGP.  This can eliminate the need to run PIM on
   the PE-CE interfaces, potentially eliminating the need to run PIM on
   the PE routers at all.
