摘　　要：避免路由环是BGP系统的基本规则,违背该规则会给Internet连通性带来严重影响。文章研究了BGP表中的环形现象。通过对RouteViews数据进行分析,给出量化结果,并讨论该现象产生原因及相关问题。Routing-loop-avoidance rule is one of the essential rules of the BGP system, and breaking the rule will produce bad influence on the Internet connectivity. By analyzing the data from Route Views, this paper examines the routing-loop phenomenon of the inter-domain routing system, provides the informative statistics and analysis. The discussion about the causes of route loops and related problems will contribute to the healthy operation of the Internet.
