Abstract: In one embodiment, a method includes determining, by a network node, that a first plurality of tunnel interfaces resides in a core region of a network and determining, by the network node, that a second plurality of tunnel interfaces resides in an access region of the network. The method also includes configuring, by the network node, a first tunnel interface as a core regional fallback path for the core region of the network and configuring, by the network node, a second tunnel interface as an access regional fallback path for the access region of the network.

Abstract: In one embodiment, a method includes receiving, by a network node, traffic within a hierarchical software-defined wide area network (SD-WAN) network. The method also includes determining, by the network node, a destination region of the traffic. The destination region is within the hierarchical SD-WAN network. The method further includes classifying, by the network node, the traffic based on a destination match condition. The destination match condition is associated with two or more destination regions.
