Abstract
Some embodiments of the invention provide a method for providing asymmetric route resolutions in an SD-WAN. The method is performed at a first edge router at a first site in a first region connected by the SD-WAN. From a first hub router of a first cluster, the method receives a flow sent by a second edge router at a second site in a second region via a first route that points to a next-hop second hub router of a second cluster. The method identifies a default second route from the first edge router to the second edge router pointing to a next-hop third hub router of the second cluster. When the first route includes secure overlay tunnels, and source addresses of the first packet flow and the first route match, the method uses the first route to send a return flow to the second edge router to ensure symmetric routing.
