Abstract: In a route management method, a configuration distribution device may create a route processing unit in at least one route processing device when there is a route management requirement, determine a route processing unit corresponding to each to-be-processed target private network, and then send configuration information of each target private network to a corresponding route processing unit, so that the route processing unit processes a route of a corresponding target private network. The at least one route processing device is created in real time based on the route management requirement, and each route processing unit can independently complete route receiving and sending and route selection of a corresponding target private network.
