Problems solved by technology

[0005] Using the central switching frame to realize network interconnection requires a single topology structure between the routers within the cluster, resulting in limited system scale and capacity, which cannot adapt to changes in network scale; routers within the cluster need to design special switching frames and dedicated interfaces with the central switching frame Connected, high design cost and not easy to expand

Abstract

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.

Description

technical field [0001] The embodiment of the present invention relates to communication technology, and in particular to a router, a virtual cluster router system and an establishment method. Background technique [0002] With the continuous development of the Internet, router cluster technology emerges as the times require. The so-called router cluster is to interconnect multiple physically independent routers to form a logically integrated router system. Each independent router is centrally managed and operates like a router, which greatly simplifies the operation and maintenance of the equipment. [0003] In the existing router cluster form, it is usually necessary to interconnect multiple independent routers in a star topology through a specific central switching frame. [0004] In the process of realizing the present invention, the inventor finds that there are at least the following problems in the prior art: [0005] Using the central switching frame to realize net...
