1. A packet detection apparatus, applied to a first provider edge (PE) and comprising:
a processor; and
a memory coupled to the processor and configured to store instructions that, when executed by the processor, cause the packet detection apparatus to be configured to:
send a detection packet to a second PE, wherein the detection packet comprises a virtual extensible local area network (VXLAN) tunnel source Internet Protocol (IP) address;
receive, through a VXLAN tunnel, a response packet in response to the detection packet, wherein the response packet comprises the VXLAN tunnel source IP address;
determine the first PE as a destination receiver of the response packet based on the VXLAN tunnel source IP address in the response packet or based on a second destination IP address in the response packet, wherein the second destination IP address is an IP address of a first customer edge (CE); and
obtain a detection result from the response packet.
