Abstract:
A WAN controller can configure a first WAN interface on a first WAN edge device to connect to a first transport network. The WAN controller can configure a second WAN interface on a second WAN edge device to connect to a second transport network. The WAN controller or the first WAN edge device, connected to a first access device of an access network, can determine the first WAN edge device has no Layer 2 connectivity to the second WAN edge device, connected to a second access device of the access network. The WAN controller or the first WAN edge device can establish a tunnel between the first WAN edge device and the second WAN interface. The WAN controller can route a specified class of WAN traffic received by the first WAN edge device from the access network through the tunnel.
