Internet Engineering Task Force (IETF) J. Korhonen, Ed. Request for Comments: 6463 Nokia Siemens Networks Category: Standards Track S. Gundavelli ISSN: 2070-1721 Cisco H. Yokota KDDI Lab X. Cui Huawei Technologies February 2012 Runtime Local Mobility Anchor (LMA) Assignment Support for Proxy Mobile IPv6 Abstract This document describes a runtime local mobility anchor assignment functionality and corresponding mobility options for Proxy Mobile IPv6. The runtime local mobility anchor assignment takes place during a Proxy Binding Update and a Proxy Binding Acknowledgement message exchange between a mobile access gateway and a local mobility anchor. The runtime local mobility anchor assignment functionality defined in this specification can be used, for example, for load- balancing purposes.

Standards Track [Page 2] RFC 6463 Runtime LMA Assignment February 2012 1. Introduction This specification describes a runtime assignment of a local mobility anchor (LMA) for the Proxy Mobile IPv6 (PMIPv6) [RFC5213] protocol. The runtime LMA assignment takes place during a Proxy Binding Update (PBU) and a Proxy Binding Acknowledgement (PBA) message exchange between a mobile access gateway (MAG) and a LMA.
