Mobile Multicast Sender Support in Proxy Mobile IPv6 (PMIPv6) Domains
draft-ietf-multimob-pmipv6-source-06
Abstract
Multicast communication can be enabled in Proxy Mobile IPv6 domains
via the Local Mobility Anchors by deploying MLD proxy functions at
Mobile Access Gateways, via a direct traffic distribution within an
ISP's access network, or by selective route optimization schemes.
This document describes the support of mobile multicast senders in
Proxy Mobile IPv6 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.
Requirements Language
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
"SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
document are to be interpreted as described in RFC 2119 [RFC2119].
