network bandwidth. When a neighbor is lost or a link is unavailable, then, the system immediately finds a feasible successor Router from the topology table and enables the alternative route. If there is no successor router in the topology table, because the neighbor of the router is used to provide route information, send query data packets to all neighbors after the route is set to active ｡ If a neighbor has a route entry to the destination, it will reply to the query and no longer spread the
