Abstract: The border gateway protocol is the inter-domain routing protocol used to exchange reachability information between autonomous systems in the global Internet. BGP is a path-vector protocol that allows each autonomous system to override distance-based metrics with policy-based metrics when choosing best route. It is possible for a group of autonomous systems to independently define BGP policies that together lead to BGP protocol oscillations that never converge on a stable routing. This paper mainly studies the routing stability of BGP-4 and the corresponding solving technology. ;;

摘要： 边界网关协议是自治域间的路由协议,用于在全球因特网之间交换网络可达性信息。是路径向量协议,在选择一个 (BGP) ASBGP最佳路由时允许每一个自治系统用基于策略的度量值来重载基于距离的度量值。将一组独立地定义策略的自治系统组织在一起时,很可BGP能就导致了协议的摆动,即不能聚集在一个稳定的路由中。该文着重分析了边界网关协议路由稳定性问题和相应的解决技术。BGPBGP-4
