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.
Status of This Memo
This document is not an Internet Standards Track specification; it is

evaluation.
This document defines an Experimental Protocol for the Internet
community. This document is a product of the Internet Engineering
Task Force (IETF). It represents the consensus of the IETF
community. It has received public review and has been approved for
publication by the Internet Engineering Steering Group (IESG). Not
all documents approved by the IESG are a candidate for any level of
