摘　　要：文章分析了校园网多出口的需求及面临的问题,指出目前常用的基于网络地址转换(NAT)的校园网多出口路由策略存在的缺陷,提出了一种结合网络地址转换、路由策略、策略路由等多种技术的多出口配置方案。并结合校园网实例实现了具体应用,实践证明该方案通过策略路由技术的灵活应用,满足了多校区多出口校园网的各种应用需求。The requirement and problems of multi- ple egress routing are analyzed. The deficiency of predominant NAT-based routing policy in multiple egress campus network is pointed out. A more suit- able configuration for multiple egress network is proposed, based on technologies such as network address translation, routing policy and policy-based routing. Specific applications are realized in the re- al campus network. It has been proved that the configuration can meet the demand of multiple egress campus network through the flexible applica- tion of policy-based？routing.
