1. A method for forwarding packets through an SD-WAN (software-defined wide area network), the method comprising:
to facilitate the forwarding of packets from a first region of the SD-WAN to a second region of the SD-WAN, and from the second region of the SD-WAN to the first region of the SD-WAN, said first region having a first hub router forwarding packets between a first set of edge routers of a first set of sites of the first region, and said second region having a second hub router for forwarding packets between a second set of edge routers of a second set of sites of the second region:
directing the first set of edge routers to (i) establish connections to the first and second hub routers, and (ii) use the first hub router as a next-hop to initiate communications with the second set of edge routers located at the second set of branch sites of the second region; and
directing the second set of edge routers to (i) establish connections to the first and second hub routers, and (ii) use the second hub router as a next-hop to initiate communications with the first set of edge routers located at the first set of branch sites of the first region.
