Abstract

Proxy Mobile IPv6 (PMIPv6) [RFC5213] extends Mobile IPv6 (MIPv6) [RFC6275] by network-based management functions that enable IP mobility for a host without requiring its participation in any mobility-related signaling. Additional network entities called Local Mobility Anchor (LMAs) and Mobile Access Gateways (MAGs) are responsible for managing IP mobility on behalf of the mobile node (MN). An MN connected to a PMIPv6 domain, which only operates according to the base specifications of [RFC5213], cannot participate in multicast communication, as MAGs will discard group packets.

  Mobile Multicast Sender Support in Proxy Mobile IPv6 (PMIPv6) Domains

Abstract

   Multicast communication can be enabled in Proxy Mobile IPv6 (PMIPv6)    domains via the Local Mobility Anchors by deploying Multicast    Listener Discovery (MLD) proxy functions at Mobile Access Gateways,    by using 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 PMIPv6 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.
