摘 要
基于策略的路由是一种比基于目的网络的路由更灵活的数据包路由和转发机制。路由器处理需要转发的数据包,通过路由图决策,路由图确定数据包的下一个路由器转发路径。该设计以校园网为背景,采用多出口周边网络方案,可以缓解CERNET与公网互联不畅的问题,但会导致周边网络路由复杂。
为此,您应该在实施此方案之前规划好您的周边网络路由,并通过掌握该流量在您的周边网络中的转发过程来有效地预留流量。外网只能访问内网记录服务器,内网主机可以自动选择出口访问外网。实验基于典型计算机网络环境对网络功能的要求,使用ENSP模拟器构建整个网络拓扑。在实现网络功能的过程中,策略路由主要用于完成组网设备的配置和最终结果的验证。

Abstract
Policy-based routing is a more flexible packet routing and forwarding mechanism than purpose-based routing.The router processes the packets that need forwarding, and the routing graph determines the next router of the packet forwarding path through the routing graph decision.The design takes the campus network as the background and adopts the multi-exit peripheral network scheme, which can alleviate the problem of poor interconnection between CERNET and public network, but will lead to complex surrounding network routing.
To this end, you should plan your peripheral network route before implementing this plan, and effectively reserve the traffic by mastering the forwarding process of the traffic in your peripheral network.The extranet can only access the Intranet record server, and the Intranet host can automatically select exits to access the extranet.Based on the functional requirements of a typical computer network environment, the whole network topology is constructed using the ENSP simulator.In the process of realizing network function, policy route is mainly used to complete the configuration and verification of final results.
Key words: strategic routing; network multi-exit; campus network; ENSP; simulation simulation
