摘要
为了解决互联网络中多种路由协议之间进行双点双向路由引入而导致次优路径问题,采用华为网络模拟器搭建实验环境对次优路径问题的产生原因进行了分析,然后提出了两种解决次优路径问题的方法:一是利用访问控制列表来匹配某条路由,然后修改该条路由的优先级;二是对外部引入路由,利用路由策略设置路由标记及过滤带标记的路由。结果表明:两种方法都能防止路由重分发中出现次优路径问题,同时也实现了链路备份和负载均衡。
In order to solve the suboptimal path problem caused by the introduction of two-point bidirectional routing between multiple routing protocols in the Internet,Huawei network simulator was used to build an experimental environment to analyze the causes of the suboptimal path problem,and then proposed two solutions.There are two ways to solve the problem of suboptimal paths:first,use access control lists to match a certain route,and then modify the priority of the route;second,introduce external routes,use routing policies to set route tags and filter tagged routes.The results show that both methods can prevent suboptimal path problems in route redistribution,and also achieve link backup and load balancing.
