Abstract:
A path detection method in a virtual extensible local area network (VxLAN), a controller, and a network device, where the controller constructs a detection packet according to a detection request and sends the detection packet to a source network device corresponding to a source VxLAN tunnel endpoint (VTEP). The source network device forwards, level by level, the detection packet to a destination network device corresponding to a destination VTEP, and reports information such as an Internet Protocol (IP) address, an outbound interface number, and an inbound interface number to the controller level by level. Therefore, a real service path may be detected.

Claim (Index 4):
The method of  claim 1 , wherein the reporting message further comprises a hop count, and obtaining the network path from the first network device to the second network device comprising:\n screening out, by the controller according to the reporting message from each level of network device, one pair of outbound interface number and inbound interface number from a plurality of reporting messages comprising a same IP address and a same hop count, hop counts in the reporting messages from all levels of network devices progressively and sequentially decrease from the first network device corresponding to the endpoint identifier of the source VTEP to the second network device corresponding to the endpoint identifier of the destination VTEP; sorting, by the controller according to the hop count in the reporting message from each level of network device, all groups that are obtained after screening and that are of IP addresses, outbound interface numbers, and inbound interface numbers; and obtaining, by the controller, the network path according to each group that is obtained after screening and sorting and that is of an IP address, an outbound interface number, and an inbound interface number.
