FAULT FIXING METHOD, DEVICE AND STORAGE MEDIUM IN SR-MPLS ANYCAST SCENARIO

摘要

Disclosed in the present application are a fault fixing method, device and storage medium in an SR-MPLS Anycast scenario. The method is executed at an edge device side configured with an Anycast-SID and comprises: once an edge device receives a message, the edge device reading a label stack carried in the message; when a stack top label of the label stack is hit in the Anycast-SID of the edge device, querying whether a fault occurs in a subsequent forwarding link corresponding to the message according to an internal layer label of the label stack; and if a fault occurs in the subsequent forwarding link corresponding to the message, using a backup device having the same Anycast-SID as the edge device to execute fast reroute processing for the message.
