摘要

When a mobile node MN moves from an access router AR 3 to another access router AR 4 , it sends a multi-binding on request to a mobility agent MA 1 and then moves ({circle around (1). Receiving the multi-binding on request, the mobility agent MA 1 voluntarily configures prospective CoA's (probable CoA's) The probable CoA's are added as forwarding addresses while an M bit is set on in an register of the mobile node MN on a binding cache ({circle around (2). When the mobility agent MA 1 receives a capsuled packet addressed to the mobile node MN thereafter, it tunnel-forwards the packet to CoA 3 , probable CoA 2 , and probable CoA 4 according to the binding cache ({circle around (3).
