Abstract
A method for providing a virtual private network by home agent in a mobile IP environment includes providing a home agent operable to receive a registration request from a foreign agent and negotiate conditions of attachment of a mobile node to the foreign agent and further operable to store an IP address of the foreign agent in response to the negotiated conditions. The method also includes receiving, at the home agent, from the foreign agent, a registration request for the mobile node. The method also includes determining, by the home agent, a virtual private network membership of the mobile node based on a characteristic associated with the mobile node. The method further includes mapping the mobile node to an identifier associated with the home agent and transmitting the mapping to the foreign agent. The identifier is indicative of the virtual private network membership of the mobile subscriber. The method also includes receiving packets containing the identifier from the foreign agent and, in response, directing the packets to an IP address associated with the virtual private network.
