     Multicast Mobility Routing Optimizations for Proxy Mobile IPv6

Abstract

   This document proposes some experimental enhancements to the base
   solution to support IP multicasting in a Proxy Mobile IPv6 (PMIPv6)
   domain.  These enhancements include the use of a multicast tree
   mobility anchor as the topological anchor point for multicast
   traffic, as well as a direct routing option where the Mobile Access
   Gateway can provide access to multicast content in the local network.
   The goal of these enhancements is to provide benefits such as
   reducing multicast traffic replication and supporting different
   PMIPv6 deployment scenarios.
