 Mobile Multicast Sender Support in Proxy Mobile IPv6 (PMIPv6) Domains
                  draft-ietf-multimob-pmipv6-source-09

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 a base solution and an experimental protocol
   to support mobile multicast senders in Proxy Mobile IPv6 domains for
   all three scenarios.  Protocol optimizations for synchronizing PMIPv6
   with PIM, as well as a peering function for MLD Proxies are defined.
   Mobile sources always remain agnostic of multicast mobility
   operations.
