Abstract
Some embodiments of the invention provide a method for interconnecting hub router clusters in an SD-WAN. The method is performed for each hub router of a first cluster and located in a first of multiple regions connected by the SD-WAN. The method establishes a connection with a respective hub router of a second cluster and located in a second of the multiple regions. The method sends, to a route reflector for the first region connected to the first cluster, a first peer-connection notification identifying the hub router as a next-hop for reaching the respective hub router. For each other hub router of the first cluster, the method receives from the route reflector a second peer-connection notification identifying the other hub router as a next-hop for reaching the other hub router's respective second cluster hub router for use in reaching edge routers connected to each other hub router's respective hub router.
