摘要： 针对BGP路由源配置错误和路由输出配置错误，提出了一种BGP路由配置错误动态检查方法。该方法通过对入境和出境路由的地址前缀进行所属关系检测来确定所声明前缀的合法性，发现路由源配置错误。依据自治系统之间的商业关系，通过分析出入境路由的AS路径属性来发现违反路由输出原则的路由输出配置错误。通过仿真实验证明了所给方法的正确性和可行性。

Abstract: A method to dynamically detect BGP configuration errors is proposed. The method focuses on two types of misconfigurations, origin misconfiguration and export misconfiguration. To find the origin misconfiguration, the method checks the prefixes of inbound or outbound routes to verify whether the prefixes announced belong to the original AS. According to the commercial relationship between ASes, the method finds the export misconfiguration by checking whether one AS in the AS-PATH violates the export guideline. Finally, the method is proved to be feasible through simulation.
