Abstract

The present application provides a bidirectional forwarding detection switching method and an edge device. The two-way forwarding detection switching method is applied to the edge device. The edge device is the first end point device of the tunnel. The edge device presets the primary path information and backup path information between the edge device and the second end point device of the tunnel. One or more pseudowires PW are established between them. The method includes: when the central processing unit CPU of the edge device detects a failure of a device other than the edge device in the main path, setting the encapsulation information as the first encapsulation information including backup path information, and transmitting the first PW corresponding to the first PW. BFD message information; when the forwarding unit of the edge device receives the service message corresponding to the first PW, it uses the first encapsulation information including the backup path information to encapsulate the service message, and forwards the obtained tunnel message; the forwarding unit receives the first PW A BFD packet information, encapsulating the first BFD packet information with the first encapsulation information, and forwarding the obtained BFD packet.

Description

technical field [0001] The present application relates to the field of communication technologies, and in particular, to a bidirectional forwarding detection and switching method and an edge device. Background technique [0002] Currently, redundant paths are often set between end devices at both ends of a tunnel to ensure that packets can be transmitted in the tunnel as much as possible. For example, two paths, one active and one standby, are deployed between the end devices at both ends of the tunnel. When a device on the main path fails, packets can be transmitted through the standby path, which involves the path switching technology. [0003] The above technologies are also often combined with a pseudo wire (Pseudo Wire, abbreviated: PW) technology to be applied to actual networking, and use Bidirectional Forwarding Detection (Bidirectional Forwarding Detection, abbreviated: BFD) to detect and protect the PW. For example, a primary and secondary path is set between the ...
