PMIPv6 Extensions for Multicast
This document describes Proxy Mobile IPv6 (PMIPv6) extensions to support IP multicast. The Mobile Access Gateway (MAG) and the Local Mobility Anchor (LMA) are the mobility entities defined in the PMIPv6 protocol. The proposed protocol extension provides; 1) a dedicated multicast tunnel (M-Tunnel) between LMA and MAG, and 2) local routing to deliver IP multicast packets for mobile nodes. This document defines the roles of LMA and MAG to support IP multicast for the mobile nodes.
