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.
