<p>A method and device for realizing unicast reverse path check. The information about that a unicast reverse path check URPF needs to be implemented is set in the route table item of the network device, the network device carries out URPF to the corresponding message according to the route table item which carries the information about that the URPF needs to be implemented. The invention can set the information about that the URPF needs to be implemented in the network device's route table in a dynamic or static manner, and so on. The embodiment of the invention can simplify the implementing progress of URPF and improve the forward performance of the network device.</p> |
