摘　　要：为优化校园网络出口结构,在GNS3仿真环境下,设计了双多宿网络路由选择仿真实验。文章给出了在校园网出口处引入双多宿ISP线路以及部署BGP、EIGRP等多种动态路由协议的网络优化方案,详细阐述了EBGP多跳、IBGP、修改BGP下一跳属性、修改BGP本地优先级属性的配置方法。测试结果表明,优化后的校园网,不仅出口链路的可靠性有较大提高,而且可使校园网用户的数据流能够按照最佳路径访问互联网资源。In order to optimize the export structure of campus network,in the GNS3 simulation environment,I designed a simulation experiment of routing selection for dual-multihoming network.This paper presents a network optimization scheme.It introduces dual-multihoming ISP lines and deploys BGP,EIGRP and other dynamic routing protocols at the outlet of campus network, and expounds in detail the configuration methods of EBGP multi-hop,IBGP,modifying BGP next-hop attributes and modifying BGP local preference.The test result proves that this scheme can solve the main problems faced by the current campus network well.The optimized campus network not only improves the reliability,but also enables the data flow of the users of the campus network to access the Internet resources according to the best path.
