Method, veneer and network equipment for sending route information

Abstract

An embodiment of the invention discloses a method, a veneer and a network equipment for sending route information which belong to the communication field; solve problem that a back board re-transmits a route information transmitted by a prior main control board after a back board updating to a new main control board, and the transmitting resource is waste. The method includes steps as follows: when the main control board runs normally, the backup board obtains a transmitting state of the route information in the main control board synchronously, and amends the route attribution in the backup board for recording the route information transmitting state; when the main control board occurs fault, the backup board becomes a new main control board, the new main control board is used for recording the route attribution of the route information transmitting state, and transmits non-transmitted route information by the prior main control board for avoiding repeating the route information. The technique scheme provided by the embodiment can be used for transmitting the route information.

Description

technical field [0001] The invention relates to the communication field, in particular to a method for sending routing information, a single board and network equipment. Background technique [0002] BGP (Border Gateway Protocol, Border Gateway Protocol) is a dynamic route discovery protocol for discovering and transferring routes between ASs (Autonomous systems, autonomous systems). Between ASs, routes are sent in units of packaged groups, that is, the received routes are sent to the corresponding neighbors in the packaged group at one time. In order to ensure the timely sending of routing information, BGP also proposes NSR (NotStop Route, non-stop routing) according to group packaging. If a fault occurs, the standby board is replaced by a new main control board, which replaces the original main control board to send routing information. During the master / standby switchover process, the inventor found that if the original main control board stored a large amount of routin...

AI Technical Summary

Problems solved by technology

During the master / standby switchover process, the inventor found that if the original main control board stored a large amount of routing information, the new main control board could not determine which routing information had been sent, and would resend the routing information, which increased the sending time. The amount of data reduces the efficiency of packaging
