摘　　要：企业园区网络出口连接运营商网络以获取ISP服务,为了保障网络可靠性和稳定性,往往设计了多个出口,实现内网数据的流量均衡和链路备份.文中的园区网存在电信、联通、教育网3个网络出口,内网数据通过预先控制的方式沿着不同的路径访问不同的网络,并可以相互切换,实现了数据分流和负载均衡.在网络搭建过程中选用锐捷系列网络设备,使用了策略路由和路由选路部署,以及调整路由协议路径成本,使数据沿着多个出口加以实现.通过策略路由的部署,网络按照设定的方案实现了按不同路径进行转发,并且实现了故障切换.通过在网络出口设备上部署策略路由,有效地控制数据流量的转发和传输,使网络运行既快速又可靠.In order to ensure the reliability and stability of the network, multiple outlets are often designed to achieve the traffic balance and link backup of Intranet data. In this paper, there are three network outlets in the campus network, such as telecommunications, interconnection and education network. The data in the Intranet can access different networks along different paths by artificial control, and can switch with each other, thus realizing data shunting and load balancing. In the process of network construction, we choose the Ruijie series network equipment, use the strategy route deployment and route selection deployment, and adjust the route cost of the routing protocol to realize it. Through the deployment of policy routing, the network realizes forwarding according to different paths and the set scheme, and achieves fault handover. By deploying policy routing on network outlet devices, the transmission and transmission of data traffic can be effectively controlled, which ensures the fast and reliable network.
