The PMIPv6 architecture defines these functional entities:
Local Mobility Anchor (LMA)
•
Mobile Access Gateway (MAG)
•
Mobile Node (MN)
•
Cellular Networks (CN)
•
The LMA is the central core element of the PMIPv6 architecture. It is the point for assigning and advertising
the MN IP addresses. The LMA establishes a bi−directional tunnel to the controller, (running release 7.3 or
later) and functions as a PMIPv6 MAG. The MAG (that is, controller) interfaces with the LMA, and performs
the mobility management on behalf of the wireless client (MN).
Other device on the network (defined as CN) will be able to reach the wireless client (MN) via its home
address through the LMA, which is advertising the reachability for the MN prefix to the CN.
For more information on the PMIPv6 Seamless IP Mobility feature, refer to Cisco Wireless Proxy Mobile
IPv6 Configuration Guide.
Here you can see the general PMIPv6 settings screen on an 8500 Controller:
Note: The PMIPv6 MAG functionality is currently only available for the Cisco 8500, 5500, and WiSM−2
Controller platforms.
Note: Release 7.3 supports communication with up to 10 LMAs, and 40,000 PMIPv6 clients.
WiFi Passpoint 1.0 (or HotSpot 2.0)
There are three technology pillars to Passpoint (HotSpot2.0): IEEE 802.11u, WPA2−Enterprise, and
EAP−based authentication.
Wi−Fi certified Passpoint (HS2.0) assures simple and secure connection to public Wi−Fi hotspots for
offloading cellular data, ensuring lower overall TCO.
HS2.0 support is available on these AP modes of operation:
