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.
