Abstract:
[RFC4761] and [RFC4762] describe a solution for Virtual Private LAN
Service (VPLS) multicast that relies on the use of point-to-point or
multipoint-to-point unicast Label Switched Paths (LSPs) for carrying
multicast traffic. This solution has certain limitations for certain
VPLS multicast traffic profiles. For example, it may result in highly
non-optimal bandwidth utilization when large amount of multicast
traffic is to be transported.
This document describes a solution for overcoming a subset of the
limitations of existing VPLS multicast solution. It describes
procedures for VPLS multicast that utilize multicast trees in the
service provider (SP) network. The solution described in this
document allows sharing of one such multicast tree among multiple
VPLS instances. Furthermore, the solution described in this document
allows a single multicast tree in the SP network to carry traffic
belonging only to a specified set of one or more IP multicast streams
from one or more VPLS instances.
