Abstract
A system and method is directed to updating information in a mobile network. A dynamic signaling routing protocol is extended over bi-directional tunneling between a mobile router and its home agent such that information associated with the home agent of the mobile router reflects roaming of the mobile router as it travels from its home network. The information is determined as a function of a characteristic associated with each link of the tunnel between the mobile router and its home agent. In one embodiment, the information includes a cost metric associated with the cost of the tunnel. The information is advertised to another router. The other router employs the information associated with the tunnel to determine a path for communication.
