Title: Multicast in BGP/MPLS VPNs and VPLS
State: Active
Authors: Rahul Aggarwal
Group: Individual Submissions (none)
Date: 2004-10-28
This document describes a solution framework for overcoming the limitations
of existing Multicast VPN (MVPN) and VPLS multicast solutions. It describes
procedures for enhancing the scalability of multicast for BGP/MPLS VPNs. It
also describes procedures for VPLS multicast that utilize multicast trees
in the sevice provider (SP) network. The procedures described here reduce
the overhead of PIM neighbor relationships that a PE router needs to
maintain for BGP/MPLS VPNs. They also reduce the state (and the overhead of
maintaining the state) in the SP network by removing the need to maintain
in the SP network at least one dedicated multicast tree per each VPN.
