METHOD AND APPARATUS FOR MONITORING VIRTUAL EXTENSIBLE LOCAL AREA NETWORK (VXLAN) TUNNEL WITH BORDER GATEWAY PROTOCOL (BGP)-ETHERNET VIRTUAL PRIVATE NETWORK (EVPN) INFRASTRUCTURE
A method and apparatus for monitoring a status of a virtual extensible local area network (VXLAN) tunnel between a first network device and a second network device are described. A first packet is received from the first network device through the VXLAN tunnel. The first packet includes a network identifier which identifies a VXLAN segment and an inner destination address that identifies the first network device within the VXLAN segment. In response to receiving the first packet, the second network device transmits, based upon the inner destination address and the network identifier, a second packet towards the first network device through the VXLAN tunnel, where the transmitting the second packet causes the first network device to determine whether the VXLAN tunnel is active.
