According to certain embodiments, a method by a network device includes receiving a handshake message for a traffic flow from a Software-Defined Wide-Area Network (SDWAN) and determining, from a traffic policy, whether the traffic flow should be symmetrical. In response to determining from the traffic policy that the traffic flow should be symmetrical, the method further includes performing a flow lookup on the traffic flow to determine if the network device originated the traffic flow. In response to determining that the network device did not originate the traffic flow, the method further includes determining a second network device that originated the traffic flow and sending the handshake message for the traffic flow to the second network device in order to maintain symmetry for the traffic flow.
