Abstract

   This document describes a solution for overcoming a subset of the
   limitations of existing VPLS multicast solutions. It describes
   procedures for VPLS multicast that utilize multicast trees in the
   sevice provider (SP) network.  One such multicast tree can be shared
   between multiple VPLS instances.  Procedures by which a single
   multicast tree in the SP network can be used to carry traffic
   belonging only to a specified set of one or more IP multicast streams
   from one or more VPLSes are also described.
