Introduction

Mobile IP is like giving an individual a local post office forwarding address when leaving home for an extended period. When mail arrives for the individual home address, it is forwarded by the local post office to the current care-of-address. Using this method, only the local post office requires notification of the individual current address. While this example represents the general concept of Mobile IP operation and functionality,

it does not represent the implementation of Mobile IP used.

A tunnel is the path taken by the original packet encapsulated within the payload portion of a second packet to some destination on the network.

A Home Agent is an AP acting as a router on the MU home network. The home agent intercepts packets sent to the MU home address and tunnels the message to the MU at its current location. This happens as long as the MU keeps its home agent informed of its current location on some foreign link.

A Foreign Agent is an AP acting as a router at the MU location on a foreign link. The foreign agent serves as the default router for packets sent out

by the MU connected on the same foreign link.

A care-of-addressis the IP address used by the MU visiting a foreign link. This address changes each time the MU moves to another foreign link.

It can also be viewed as an exit point of a tunnel between the MU home agent and the MU itself.

The S24 Mobile IP (roaming across routers) feature enables an MU on the Internet to move from one subnet to another while keeping its IP address unchanged.

To configure this feature, see section 2.4: ”Configuring System Parameters” on page 59. The Mobile IP feature is not available if either Kerberos or EAP-TLS have been enabled as access point security measures.
