    This behavior is called asymmetric routing. Packets follow different paths depending on the direction. Asymmetric routing is one of the two most common causes of flooding.

    We recommend that you do not apply Unicast RPF where there is a chance of asymmetric routing, unless you configure access control lists (ACLs) to allow the device to accept incoming packets.
