A node, in a first network, includes circuitry configured to determine a next hop as decided by Border Gateway Protocol (BGP) is an anycast prefix to a Route Reflector (RR) interconnecting the first network with a second network, responsive to the next hop being the anycast prefix to the RR, create a tunnel with a destination based on the anycast prefix, and utilize the tunnel for traffic having the next hop as the anycast prefix to the RR. The anycast prefix is assigned to two or more RRs interconnecting the first network and the second network. A first path is decided by BGP based on a BGP Path Selection Algorithm that is independent of a second path determined by Interior Gateway Protocol (IGP). The first path and the second path can be different, and wherein tunnel is utilized to ensure the traffic always follows the first path.

Some embodiments of the invention provide a method for providing dynamic edge-to-edge support across multi-hops in an SD-WAN connecting multiple regions. The method is performed at a first route reflector for a first of the multiple regions. The method receives, from a first edge router at a first site of the first region, a first request for endpoint information associated with a second edge router at a second site of a second region. After determining that the first route reflector does not have a direct connection to the second edge router, the method identifies a next-hop hub router for reaching the second edge router. The method sends a second request to the identified next-hop hub router to request the identified next-hop hub router to forward endpoint information for the second edge router to the first edge router for use in establishing a dynamic edge-to-edge connection with the second edge router.
