Abstract:
A path detection method and apparatus, where the method includes generating M virtual extensible local area network (VXLAN) probe packets according to a source User Datagram Protocol (UDP) port number, a destination UDP port number, and a probe identifier when there are multiple equivalent paths between a source VXLAN tunnel endpoint (VTEP) and a destination VTEP, sending the M VXLAN probe packets to the source VTEP to forward the M VXLAN probe packets to the destination VTEP, receiving VXLAN advertisement packets from the source VTEP, the destination VTEP, and intermediate nodes in the multiple equivalent paths according to the M VXLAN probe packets, and detecting, according to the VXLAN advertisement packets, whether a fault occurs in a path of the multiple equivalent paths between the source VTEP and the destination VTEP.

Claim (Index 2):
The method according to  claim 1 , wherein detecting whether the fault occurs in the path of the equivalent paths between the source VTEP and the destination VTEP comprises determining, according to an Internet Protocol (IP) address of the source VTEP, an IP address of the destination VTEP, a Layer 4 port number of the source VTEP, a Layer 4 port number of the destination VTEP, a protocol type between the source VTEP and the destination VTEP, a time to live (TTL), and an ingress port, an egress port, and a system identifier of a device sending each VXLAN advertisement packet, whether the fault occurs in the path of the equivalent paths, and wherein the IP address of the source VTEP, the IP address of the destination VTEP, the Layer 4 port number of the source VTEP, the Layer 4 port number of the destination VTEP, the protocol type between the source VTEP and the destination VTEP, the TTL, the ingress port, the egress port, and the system identifier of the device sending each VXLAN advertisement packet are carried in the VXLAN advertisement packets.
