An embodiment of the present invention provides a virtual cluster router system, where the system includes a control device and at least two forwarding routers Router; the at least two forwarding Routers establish communication with other network devices outside the system through respective external interface; and control management channels are established between the control device and the at least two forwarding Routers. The control device combines an external routing information base of the system and an internal routing information base of the system to generate a final forwarding information base, and sends the final forwarding information base to the at least two forwarding Routers through the control management channels. In addition, embodiments of the present invention provide a corresponding router and method for establishing a virtual cluster router. A topology in the virtual cluster router is not limited in the system; and separation of control and forwarding is implemented, thereby improving flexibility and reliability of network extension. |
