摘　　要：为了解决大型网络中多种动态路由协议之间进行双点双向路由引入而产生路由环路和次优路径问题,采用模拟器搭建OSPF和IS-IS路由协议相互引入实验,对次优路径和路由环路问题的产生原因进行了分析,然后提出了解决路由环路和次优路径问题的方法:对外部引入路由,利用路由策略设置路由标记,然后过滤带标记的路由。结果表明:该方法能有效防止路由引入中出现的路由环路和次优路径问题,同时还能实现负载均衡。In order to solve the routing loop and suboptimal path problems caused by the introduction of two-point bidirectional routing between multiple dynamic routing protocols in large networks,a simulator was used to build an experiment of mutual introduction of OSPF and IS-IS routing protocols,and the causes of suboptimal paths and routing loops were analyzed.Then,a method to solve the routing loop and suboptimal path problems was proposed:for external introduction of routing,routing tags were set using routing policies,and then the marked routes were filtered.The results show that this method can effectively prevent routing loops and suboptimal path problems in routing introduction,and can also achieve load balancing.
