Base Deployment for Multicast Listener Support in Proxy Mobile IPv6 (PMIPv6) Domains

Abstract

This document describes deployment options for activating multicast listener functions in Proxy Mobile IPv6 domains without modifying mobility and multicast protocol standards. Similar to home agents in Mobile IPv6, Local Mobility Anchors of Proxy Mobile IPv6 serve as multicast subscription anchor points, while Mobile Access Gateways provide Multicast Listener Discovery (MLD) proxy functions. In this scenario, mobile nodes remain agnostic of multicast mobility operations. Support for mobile multicast senders is outside the scope of this document.
