AI Technical Summary
Technical Problem
After a router restarts abnormally, the Link State Advertisement (LSA) from before the restart remains in the network, causing incorrect route calculation results and creating a routing black hole.
Method used
The problem of LSA remnants can be resolved by detecting the database description (DD) messages sent by the second device, regenerating and sending link state announcements with updated sequence numbers, or sending target messages indicating delayed migration of neighbor states.
Benefits of technology
It effectively eliminates routing black holes, ensures the accuracy of routing calculation results, and avoids errors caused by LSA residues.

Abstract
The invention provides a routing error processing method and device and related equipment, and relates to the technical field of communication. The method is executed by first equipment and comprises the following steps: detecting a database description (DD) message sent by second equipment under the condition that the first equipment is abnormally restarted, and regenerating and sending a second link state notification when the DD message contains a first link state notification of the first equipment; wherein the serial number of the first link state announcement is greater than the serial number of the link state announcement existing in a local database; or, sending the first target message to the second device; wherein the first target message comprises a first identifier, and the first identifier is used for indicating a delayed migration neighbor state. According to the scheme provided by the invention, the problem that the routing calculation result is wrong after the routing is restarted is solved.
