Abstract: Techniques for achieving hybrid control over overlay and underlay path selection by integrating underlay path identities into software-defined wide area network (SD-WAN) sessions to create individual SD-WAN sessions for each underlay path. The techniques may include receiving first path identification data associated with an underlay path of an overlay network domain that is disposed between a first edge node and a second edge node of an SD-WAN system. Based on the first path identification data, an SD-WAN session may be generated that is to utilize the underlay path for sending traffic through the overlay network domain. In some examples, the underlay path may be mapped to the SD-WAN session and the SD-WAN session may be bound to a data plane output forwarding chain associated with the underlay path such that the traffic sent over the SD-WAN session traverses the underlay path of the overlay network domain.
