Abstract
Techniques are described for forming on-demand mesh connections between spoke routers of a Software-Defined Wide Area Network (SD-WAN) arranged in a hub-and-spoke topology. A first spoke router modifies the first packet to include metadata specifying first reachability information and first Internet Protocol (IP) address information for the first spoke router. The first spoke router forwards the first packet to a hub router for forwarding to a second spoke router. The first spoke router receives a second packet from the hub router that includes metadata specifying second reachability information and second IP address information for the second spoke router. In response to determining that the first reachability information is compatible with the second reachability information, the first spoke router initiates a peering connection with the second spoke router along a path which bypasses the hub router for forwarding subsequent packets of the forward packet flow.
