Abstract:
A method and apparatus of updating a forwarding plane of a network element in response to receiving a mobility event is described. The network element receives a mobility message indicating a mobile node has coupled to a new access port associated with the network element. The message further indicates that the mobile node moved from an old access port to a new access port. The network element adds an entry in a forwarding table of the old egress engine to redirect a set of packets destined to the mobile node to a new egress engine, where the new egress engine is associated with the new access port. Furthermore, the network element redirects the set of packet from the old egress engine to the new egress engine.
