Method and device for updating mstp neighbor table

Abstract

The application provides a method and device for updating the MSTP neighbor table, the method comprising: when the network topology changes, recording the MSTP port whose state changes; setting a state change flag for the MSTP port whose state changes; starting the MSTP protocol, Clearing the neighbor entry of the MSTP port with the status change flag set based on the MSTP protocol. In the present application, because the ports that have not changed state during the topology change are no longer cleared, the problem of slow convergence speed in the prior art can be solved.

Description

technical field

[0001] The present application relates to the field of communication technologies, and in particular, to a method and apparatus for updating a MSTP (Multiple Spanning Tree Protocol, Multiple Spanning Tree Protocol) neighbor table. Background technique

[0002] In a switching network, MSTP can "prune" a ring network into a ring-free tree network, thus avoiding the proliferation and infinite looping of packets in the ring network. At the same time, MSTP also has a link backup function. When the network topology changes, the original backup link can be switched to the new main link to realize link switching and convergence of network traffic.

[0003] In the prior art, when the network topology changes, the network device clears the neighbor entries of all non-current ports, and then re-learns the neighbor entries of the port. Because many ports in the neighbor table entry of the port do not have state changes, the convergence speed of the prior art is relative...
