Abstract: Disclosed is a method that includes receiving, at a layer 2 switch, a first message to establish a fast re-switch tunnel between the layer 2 switch and a standby wireless controller and receiving, at the layer 2 switch, a second message to trigger use of the fast re-switch tunnel. The switch receives data and forwards the data to the standby wireless controller through the fast re-switch tunnel. Once MAC tables are updated for the standby wireless controller, the fast re-switch tunnel can be torn down.

Abstract: A method is provided in one example embodiment and includes configuring on a network element a first tunnel from the network element to a first network, wherein the configuring comprises mapping a nexthop address of the local network element to a transport address of the tunnel on the network to create a first nexthop-to-transport mapping for the network element; and advertising the first nexthop-to-transport mapping along with routing information for the network element to remote network elements.
