Support Multicast Services Using Proxy Mobile IPv6
This document describes how multicast mobility services can be supported with Proxy Mobile IPv6 [RFC5213], Multicast Listener Discovery (MLD) [RFC3810], and Internet Group Management Protocol (IGMP) [RFC3376]. Specifically, this document analyzes scenarios for multicast listener mobility. It proposes the use of a dedicated Local Mobility Anchor as the topological anchor point for multicast traffic, while the Mobile Access Gateway serves as an IGMP/MLD proxy. There are no impacts to the Mobile Node to support multicast listener mobility.
