      Local Mobility Anchor (LMA) Discovery for Proxy Mobile IPv6

Abstract

   Large Proxy Mobile IPv6 deployments would benefit from a
   functionality where a Mobile Access Gateway could dynamically
   discover a Local Mobility Anchor for a Mobile Node attaching to a
   Proxy Mobile IPv6 domain.  The purpose of the dynamic discovery
   functionality is to reduce the amount of static configuration in the
   Mobile Access Gateway.  This document describes several possible
   dynamic Local Mobility Anchor discovery solutions.

1.  Introduction

   A Proxy Mobile IPv6 (PMIPv6) [RFC5213] deployment would benefit from
   a functionality where a Mobile Access Gateway (MAG) can dynamically
   discover a Local Mobility Anchor (LMA) for a Mobile Node (MN)
   attaching to a PMIPv6 domain.  The purpose of the dynamic discovery
   functionality is to reduce the amount of static configuration in the
   MAG.  Other drivers for the dynamic discovery of an LMA include LMA
   load balancing solutions and selecting an LMA based on desired
   services (i.e., allowing service-specific routing of traffic)
   [RFC5149].  This document describes several possible dynamic LMA
   discovery approaches and makes a recommendation of the preferred one.

   The following list briefly introduces solution approaches that will
   be discussed in this document.  The approaches discussed do not
   include all possible discovery mechanisms, but are limited to those
   considered to fit most simply into the PMIPv6 environment.
