Abstract

The present application provides a loop detection method, device, tunnel endpoint device and storage medium. The tunnel endpoint device detects whether the packet is the first loop detection packet by obtaining the packet from the AC port; if the packet is the first loop detection packet, obtains the Initial VXLAN ID; compare the initial VXLAN ID with the VXLAN ID of the VSI corresponding to the AC port that received the first loop detection message; if they are the same, determine that there is a loop in the transmission path of the first loop detection message . In this way, it is implemented to detect whether there is a loop in the transmission path of the first loop detection message.

Description

technical field [0001] The present application relates to the communication field, and in particular, relates to a loop detection method, device, tunnel endpoint device, and storage medium. Background technique [0002] Please refer to figure 1 , the tunnel endpoint device in the virtual extended LAN can send packets to the core network through the tunnel, and can also send packets to the layer-2 network connected to it at the same time. figure 1 Include two tunnel endpoint devices, namely device A and device B. After device A sends a packet to the Layer 2 network, the packet may pass through Site A to Site B, and then Site B sends the packet to Device B through the Layer 2 network interface. Device B further encapsulates the message and sends it to device A through the tunnel. Then it can be seen that the transmission path of the message generates a loop. [0003] However, when the current tunnel endpoint device receives the packet carrying the loop detection identifier...
