Internet Engineering Task Force (IETF) D. Patki Request for Comments: 8127 S. Gundavelli Category: Standards Track Cisco ISSN: 2070-1721 J. Lee Sangmyung University Q. Fu China Mobile L. Bertz Sprint August 2017 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.

Standards Track [Page 2] 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 MAGShow full document text
