               Heartbeat Mechanism for Proxy Mobile IPv6

Abstract

   Proxy Mobile IPv6 (PMIPv6) is a network-based mobility management
   protocol.  The mobility entities involved in the Proxy Mobile IPv6
   protocol, the mobile access gateway (MAG) and the local mobility
   anchor (LMA), set up tunnels dynamically to manage mobility for a
   mobile node within the Proxy Mobile IPv6 domain.  This document
   describes a heartbeat mechanism between the MAG and the LMA to detect
   failures, quickly inform peers in the event of a recovery from node
   failures, and allow a peer to take appropriate action.

1.  Introduction

   Proxy Mobile IPv6 (PMIPv6) [RFC5213] enables network-based mobility
   for IPv6 hosts that do not implement any mobility protocols.  The
   protocol is described in detail in [RFC5213].  In order to facilitate
   the network-based mobility, the PMIPv6 protocol defines a mobile
   access gateway (MAG), which acts as a proxy for the Mobile IPv6
   [RFC3775] signaling, and the local mobility anchor (LMA), which acts
   similar to a home agent, anchoring a mobile node's sessions within a
   PMIPv6 domain.  The LMA and the MAG establish a bidirectional tunnel
   for forwarding all data traffic belonging to the mobile nodes.
