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
heartbeat interval can potentially create considerable signaling load
on the local mobility anchor (LMA). This document provides a new
option to enable the LMA to control various parameters on the MAG
