Diameter Support for Proxy Mobile IPv6 Localized Routing
Abstract
In Proxy Mobile IPv6, packets received from a Mobile Node (MN) by the
Mobile Access Gateway (MAG) to which it is attached are typically
tunneled to a Local Mobility Anchor (LMA) for routing. The term
"localized routing" refers to a method by which packets are routed
directly between an MN's MAG and the MAG of its Correspondent Node
(CN) without involving any LMA. In a Proxy Mobile IPv6 deployment,
it may be desirable to control the establishment of localized routing
sessions between two MAGs in a Proxy Mobile IPv6 domain by requiring
that the session be authorized. This document specifies how to
accomplish this using the Diameter protocol.

RFC 7156 PMIPv6 Localized Routing Support April 2014
1. Introduction
Proxy Mobile IPv6 (PMIPv6) [RFC5213] allows the Mobile Access Gateway
(MAG) to optimize media delivery by locally routing packets from a
Mobile Node (MN) to a Correspondent Node (CN) that is locally
attached to an access link connected to the same Mobile Access
Gateway, avoiding tunneling them to the Mobile Node's Local Mobility
Anchor (LMA). This is referred to as "local routing" in RFC 5213
[RFC5213]. However, this mechanism is not applicable to the typical
scenarios in which the MN and CN are connected to different MAGs and
are registered to the same LMA or different LMAs. [RFC6279] takes
those typical scenarios into account and defines the problem
statement for PMIPv6 localized routing. Based on the scenarios A11,
A12, and A21 described in [RFC6279], [RFC6705] specifies the PMIPv6
localized routing protocol that is used to establish a localized
