    Abstract: Disclosed are a routing information transmission method and apparatus, and a communication system, and belong to the field of communication technologies. The routing information transmission method is applied to a system including data middleware and a routing information base (RIB), and the data middleware communicates with the RIB. The data middleware may obtain routing information from the RIB, and send the routing information obtained from the RIB to a third-party consumer device. In addition, the data middleware may also obtain routing information from a third-party producer device, and send the routing information obtained from the third-party producer device to the RIB. Therefore, according to technical solutions provided herein, the routing information included in the RIB is openly exported, and the routing information generated by the third-party producer device is imported into the RIB.

    Abstract: A routing processing method implemented by a first network device, where a plurality of routing processing components run on the first network device and implement a same routing processing function. The method includes obtaining, from the routing processing components, routing processing results based on same input routing information, analyzing the routing processing results to obtain an analysis result, selecting, based on the analysis result, a first routing processing result from the routing processing results, and executing a corresponding action based on the first routing processing result.

    Abstract: A method includes: establishing, by a first network device, a first BMP session with a second network device, and establishing a second BMP session with a third network device; receiving a first BGP route set sent by the second network device, where the first BGP route set includes a BGP route sent by the second network device to the third network device; receiving a second BGP route set sent by the third network device, where the second BGP route set includes the BGP route received by the third network device from the second network device; and when detecting that the second BGP route set includes a first BGP route but the first BGP route set does not include the first BGP route, determining the first BGP route as an unavailable route.

    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.
