Dual Homed Access in Virtual Private Multicast Service
Xinquan Zhang, Bo Wu, Jian Luo, Ran Chen · 2009
Virtual Private Multicast Service (VPMS) is defined as a Layer 2 VPN service. It provides point-to-multipoint connectivity for a variety of Layer 2 technologies, including Frame Relay, ATM, Ethernet, PPP, etc, across an IP or MPLS-enabled IP Packet Switch Network (PSN). It is often required for redundant access between two VPMS PEs to which a CE is attached, called dual-homed. This document describes how dual- homed access can be achieved in the context of BGP-based VPMS.
