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 routing path between two Mobile Access Gateways in a PMIPv6 domain.

         Diameter Support for Proxy Mobile IPv6 Localized Routing


   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.
