摘要

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 real campus network, it proves that the configuration can meet the demand of multiple egress campus network through the flexible application of policy-based routing.%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。
