       Mobile Access Gateway Configuration Parameters Controlled
                      by the Local Mobility Anchor

Abstract

   This specification defines a new extension,
   LMA-Controlled-MAG-Session-Params, to Proxy Mobile IPv6.  This option
   can be used by the local mobility anchor (LMA) in a Proxy Mobile IPv6
   domain for signaling a mobile access gateway (MAG) on enforcing
   specific values for various configuration parameters such as
   heartbeat and binding refresh parameters.

RFC 8127       LMA-Controlled MAG Configuration Parameters   August 2017

1.  Introduction

   A large Proxy Mobile IPv6 (PMIPv6) [RFC5213] deployment, such as
   residential deployment, can have tens of thousands of mobile access
   gateways (MAGs) spread across geographical locations.  While it can
   be operationally challenging to manage such a large number of MAGs,
   it can also be very difficult to ensure configuration consistency
   across all the MAGs if they are not centrally managed.  Configuring
   aggressive values of parameters such as re-registration timeout and
