Proxy Mobile IPv6
(PMIPv6) is a network-based mobility management protocol that supports a mobile
node by acting as the proxy for the mobile node in any IP mobility-related
signaling. The mobility entities in the network track the movements of the
mobile node and initiate the mobility signaling and set up the required routing
The main functional
entities are the Local Mobility Anchor (LMA) and Mobile Access Gateway (MAG).
The LMA maintains the reachability state of the mobile node and is the
topological anchor point for the IP address of the mobile node. The MAG
performs the mobility management on behalf of a mobile node. The MAG resides on
the access link where the mobile node is anchored. The controller implements
the MAG functionality.
In the Cisco 5500
Series, Cisco WiSM2, and Cisco 8500 Series controllers, PMIPv6 MAG support for
integration with LMA such as Cisco ASR 5000 Series in cellular data networks.
For PMIPv6 clients,
Cisco WLC supports both central web authentication and local web
PMIPv6 is supported
for clients with 802.1X authentication. After the 802.1X authentication is
complete, the Cisco AP starts the PMIPv6 signaling for the client.
