 Mobile Multicast Sender Support in Proxy Mobile IPv6 (PMIPv6) Domains
                  draft-ietf-multimob-pmipv6-source-03

Abstract

   Multicast communication can be enabled in Proxy Mobile IPv6 domains
   via the Local Mobility Anchors by deploying MLD Proxy functions at
   Mobile Access Gateways, via a direct traffic distribution within an
   ISP's access network, or by selective route optimization schemes.
   This document describes the support of mobile multicast senders in
   Proxy Mobile IPv6 domains for all three scenarios.  Protocol
   optimizations for synchronizing PMIPv6 with PIM, as well as extended
   MLD Proxy functions are presented.  Mobile sources always remain
   agnostic of multicast mobility operations.
