So cisco company puts forward to EIGRP ( enhanced interior gateway routing protocol ), it takes in the advantages of RIP and OSPF. Now EIGRP is widely used in cisco router. 于是cisco公司推出了结合两种优点的平衡混合型路由协议――EIGRP(增强型内部网关路由协议),该协议为cisco公司的专有协议,在cisco路由器上用的十分普遍。
Both RIP and OSPF are interior gateway protocols, one is a distance vector routing protocol and the other is a link state routing protocol. This essay will illustrate why OSPF has replaced RIP by analysis these two protocols. RIP和OSPF是两种内部路由协议,一种属于距离向量协议,一种属于链路状态协议.本文通过对这两种协议的分析比较说明了OSPF取代RIP的原因。
Within the AS, Interior Gateway Protocols are used to exchange routing information, e.g. Open Shortest Path First ( OSPF ), The Border Gateway Protocol ( BGP ) is an inter-Autonomous System ( AS ) routing protocol. 互联网上自治系统内部通过内部网关协议交换局部路由信息,如开放最短路由优先协议OSPF。
OSPF protocol is one of the widely used interior gateway routing protocols. In the paper, a network topology model and an arithmetic based on it are presented, which are applied in OSPF protocol testing. OSPF协议是一种广泛使用的内部网关路由协议,文中提出了一种用于OSPF协议测试的网络拓扑建模方法以及相关算法。
