     Multicast Mobility Routing Optimizations for Proxy Mobile IPv6
                   draft-ietf-multimob-pmipv6-ropt-03

Abstract

   The MULTIMOB group has specified a base solution to support IP
   multicasting in a PMIPv6 domain [RFC6224].  In this document, some
   enhancements to the base solution are described.  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 MAG can provide access to multicast content
   in the local network.  These enhancements provide benefits such as
   reducing multicast traffic replication and supporting different
   PMIPv6 deployment scenarios.
