摘　　要：为了保证企业园区中网络的可靠性与流量的分担负载,会存在多条到达同一目的的路由条目,部署在不同的路由协议或者路由进程之中,为了规避路由环路与次优路径的存在,需要使用策略路由对路由传输路径进行控制。通过在多出口网络中使用tag作为策略路由属性,可以实现对路由的有效方便控制,并对路由进行过滤。本文实现了在策略路由中使用tag进行部署,并对路由传输路径进行选择与主备链路切换。In order to ensure the reliability of the network in the enterprise gardens and the load sharing of traffic,there will be multiple routing entries to the same destination to be deployed in different routing protocols or routing processes.In order to bypass routing loops and sub-optimal paths,policy routing is needed to control the routing transmission path.By using tag as a policy routing attribute in a multi-outlet network,effective and convenient control of routing can be achieved,and routing can be filtered.This paper implements the deployment of tags in policy routing,and selects routing transmission paths for the switch between primary and alternative links.
