A first virtual interface (VI) is provided on the second network device, and assigned to the first tunnel. Information related to the first tunnel and the first VI is passed to a third network device, which is a member of a cluster with the second network device. A second tunnel is provided across the layer 3 network from the third device to the first network device, and a second virtual interface (VI) is provided on the third network device, and assigned to the second tunnel. Forwarding information is exchanged between the second network device and the third network device. The second network device and the third network device provide forwarding redundancy service to the first network device.
