Method, apparatus and system for eliminating route oscillation in neighbor reconstruction

The embodiment of the invention provides a method, apparatus and system for eliminating router vibration in a neighbor rebuilding, relating to the communication technical field, improving the reliability and the stability of the router. The system comprises a first router and a second router, the first router preserves link state information 1 generated before neighborly rebuilding the second router. When the second router and the first router are neighborly rebuilt, and according to the abstract of the link state information 1 transmitted by the first router, the second router judges that the link state information 2 generated during neighbor rebuilding is older than the link state information 1 or the link state information 2 is not generated, the second router inhibits the synchronous LSDB with the first router; when the second router generates the link state information 3 for ensuring that the first router judges the link state information 1 is older than the link state information 3 and transmits the lin
