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.

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. The runtime LMA
