Extensions to the Proxy Mobile IPv6 (PMIPv6) Access Network Identifier
Option
Abstract
The Access Network Identifier (ANI) mobility option was introduced in
RFC 6757, "Access Network Identifier (ANI) Option for Proxy Mobile
IPv6". This enables a Mobile Access Gateway (MAG) to convey
identifiers like the network identifier, geolocation, and operator
identifier. This specification extends the Access Network Identifier
mobility option with sub-options to carry the civic location and the
MAG group identifier. This specification also defines an ANI Update-
Timer sub-option that determines when and how often the ANI option
will be updated.

RFC 7563 Extensions to ANI June 2015
1. Introduction
"Access Network Identifier (ANI) Option for Proxy Mobile IPv6"
[RFC6757] introduced the ANI mobility option. This enabled a Mobile
Access Gateway (MAG) to provide the Network-Identifier, Geo-Location,
and Operator-Identifier sub-options. When the access network is
WLAN, the Network-Identifier sub-option may contain the Service Set
Identifier (SSID) and the Basic Service Set Identifier (BSSID) of the
Access Point (AP) and the geolocation of the AP, and the Operator-
Identifier may contain the realm of the operator managing the WLAN.
The MAG sends the above information to the Local Mobility Anchor
(LMA). The LMA may use this information to determine access-network-
