Abstract

The invention provides a method and a device for updating an MSTP (Multiple Spanning Tree Protocol) neighbor table. The method comprises the steps of recording an MSTP port with a state change when a network topology changes; setting a state change mark for the MSTP port with the state change; and starting an MSTP, and removing neighbor table items of the MSTO port with the state change mark based on the MSTP. In the method, as ports without the state change in the network topology are no longer eliminated, the problem of relatively 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 device for updating an MSTP (Multiple Spanning Tree Protocol, Multiple Spanning Tree Protocol) neighbor table. Background technique [0002] In a switched network, MSTP can "prune" the loop network into an acyclic tree network, thereby avoiding the proliferation and infinite loop of packets in the loop 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 a 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 all the neighbor entries of the non-current port, and then relearns the neighbor entries of the port. Because many ports in the neighbor entries of the port do not undergo state changes, the convergence speed of the prior art is relatively s...
