Embodiment Construction
[0050] The core idea of the present invention is to judge whether the next hop in the routing table is valid by sending the next hops of all routes in the routing table of the routing device to the next hop of the routing table respectively. If the next hop of the route is valid, the route is valid; otherwise, the next hop of the route is considered to be invalid, and the route is invalid; Packet forwarding.
[0051] The core idea of the present invention can be realized by the following method: determine whether the next-hop network equipment of all routes in the routing table of the routing equipment is valid, because only the network equipment with the next-hop effective can carry out normal message forwarding, through Detect whether the next-hop network devices of all routes in the routing table of the routing device are valid to optimize the routing table in the routing device, and then perform packet forwarding control according to the optimized routing table.
