摘　　要：提出了一种利用BGP特定的MinimumRouteAdvertisementInterval(MRAI)定时器的非对称设置来消除BGP持续性路由振荡,从而增强BGP路由稳定性的方法·通过利用BGP活动序列图,对BGP路由振荡系统的动态行为进行了详细分析,深入地理解了路由振荡发生时BGP系统的动态行为特征·根据所获得的动态行为特征,给出了消除路由振荡,增强BGP路由稳定性的非对称配置MRAI的方法·同时,利用仿真手段,分析并比较了对称MRAI和非对称MRAI的设置方法对于BGP路由稳定性和收敛性的影响·This paper shows a method of asymmetric configuration for a BGPspecific timer,Minimum Route Advertisement Interval (MRAI),which can supperess BGP route socillations and enhance BGP routing stability. BGP evaluation state and evaluation graph were used to analyze the dynamic behavior of a typical trinode BGP route oscillations system in details and understand the behavior characteristic while the system oscillating. According to these results,a method of asymmetric configuration for MRAI was present to change the dynamic behavior of oscillations system and improve the convergence properties of BGP system.
