  • Patent number: 8842603
    Abstract: A method (200) and apparatus for determining whether a network (111) associated with a foreign agent (104) is multiple IP address interface compatible in a mobile node (101) is provided. The foreign agent (104), upon detection of the mobile node (101), composes an agent advertisement (400) that includes one or more flag bits (405). The foreign agent (104) sets one of the one or more flag bits (405) to indicate multiple IP address interface compatibility. Upon receiving the agent advertisement (400), the mobile node (101) configures itself for multiple IP address interface datagram communication. Where the mobile node (101) has not already received a primary IP address (617) from the foreign agent (104), it requests one. The mobile node (101) then requests a secondary IP address (618) from a home agent (103) through the foreign agent (104).
