The project for the Zhengzhou companies of an enterprise network, for the company business division and corporate development trend, in the layout information point can fully consider its development, combined with the company structure, adopts the corresponding equipment and technology selection. According to the enterprise network overall structure analysis, adopt three layers of structure network to realize data. Communication to share the load, and the access layer, convergence layer and core layer, access layer mainly realizes the information point of access convergence layer and access layer device, the second line of a couplet, a core layer equipment, play a bridging role, convergence layer achieve efficient data forwarding. We adopt the mainstream OSPF protocol as a layer three device learning routing manner, the agreement has open sex, be support of the majority of manufacturers, the core equipment division head
