【摘要】 IP路由设计是校园网络在逻辑实现上的核心,合理的IP路由设计会使网络具有较高的性能。根据校园网络的拓扑和流量分布情况,按照分层设计思想,通过应用VLSM,提出了校园网络IP分层寻址和聚合路由设计方法。在此基础上,结合常用路由协议,具体提供了聚合路由的实施策略。对有类路由协议RIP和IGRP、无类路由协议EIGRP和OSPF情况下的不邻接网络、子网粒度问题作了重点分析实现,从而有效减少网络通信流量和路由选择表大小,以增强网络的可管理性、可靠性和可扩展性。更多还原

【Abstract】 IP routing design is a vital part of the campus logical network. According to the hierarchical design model, a way of hierarchical ip addressing has been offered in this article. By understanding of traffic flow, using a VLSM-designed network, the paper describes and gives examples of route summarization, including implementation considerations. By studying the discontinuous subnets, and regulating the scale of subnets granularity, the paper presents a useful approach to campus networking, in which class routing protocol such as RIP and IGRP or classless routing protocol such as OSPF and EIGRP is used. As a result, reduced number of routing table entries and efficient allocation of addresses make a campus network more extendable and manageable.更多还原
