基于导出策略的路由配置错误检测方法

BGP Configuration Errors Detection Method Based on Exporting Policy

针对域间路由中易出现的路由配置疏忽,避免因不恰当配置引起域间路由不稳定事件,提出一种有效的路由配置错误检测方法。通过应用推断的域间路由导出策略,对路由宣告的前缀进行分析,检测出源配置错误和导出配置错误的潜在性,其间考虑选性路由对前缀宣告造成的影响,从而减少误判的可能性。实验结果表明,该方法利用较少的局部路由信息,可快速有效的检测出潜在的路由配置错误并辅助提升网络性能。

In order to find configuration faults in AS border gate router and avoidinter- domain routing instability events, a valid routing misconfiguration detecting method was presented. The method focuses on detection of AS origin misconfiguration and export misconfiguration by analyze outbound routing announcement errors and analyzes the influence caused by selective announce- ment according to exporting policy. The experiment results shows that potential routing misconfiguration can be detected availably by using less local routing information and improve the path selective and damping instability.
