Title: Supporting IP Multicast over VPLS
State: Active
Authors: Yetik Serbest

Date: 2004-11-29
In Virtual Private LAN Service (VPLS), the PE devices provide a logical
interconnect such that CE devices belonging to a specific VPLS instance
appear to be connected by a single LAN. A VPLS solution performs
replication for multicast traffic at the ingress PE devices. When
replicated at the ingress PE, multicast traffic wastes bandwidth when 1.
Multicast traffic is sent to sites with no members, and 2. Pseudo wires to
different sites go through a shared path. This document is addressing the
former by IGMP and PIM snooping.
