PMIPv6 Extensions for PIM-SM
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 and act as PIM-SM routers. The proposed protocol extension addresses the tunnel convergence problem and provides seamless handover. This document defines the Proxy Binding Update and the Proxy Binding Acknowledgement messages with multicast extension.
