A virtual cluster routers system is provided in the embodiments of the present invention. The system includes a control device and at least two forwarding routers. The at least two forwarding routers respectively establish the communication with other network devices outside the system via respective external connection interfaces. The control management channels are respectively established between the control device and each of the at least two forwarding routers. The control device combines the external routing information base of the system with the internal routing information base of the system, to generate a final forwarding information base, and transmits the final forwarding information base to the at least two forwarding routers through the control management channels. Moreover, a corresponding router and a method for establishing virtual cluster routers are provided in the embodiments of the present invention. The system does not limit the internal topological structure of the virtual cluster routers, realizes the separation of control and forwarding, and enhances the flexibility and reliability of the network expanding. |
