Abstract

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.

       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.
