摘　　要：开放式最短路径优先协议(Open Shortest Path First,OSPF)是一种基于链路状态的内部网关协议,其自身广泛的适应范围、较强的快速收敛能力、成熟的防环机制、严格的区域划分、层次的路由分级、科学的生成树算法等特性使其快速地从各类协议中脱颖而出,与中间系统到中间系统(Intermediate System to Intermediate System,ISIS)共同成为内部网关协议的主流。OSPF协议主要是通过发送组播报文、建立邻接关系、泛洪链路状态通告(Line State Advertisement,LSA)、计算路由并转发的方式,实现自治域内路由的交换与转发。基于此,主要对OSPF网络中几种常见特性进行探究。Open Shortest Path First(OSPF)Protocol,which is an internal gateway protocol based on link state.Its own wide range of adaptations,strong fast convergence,mature loop detection mechanism,strict region partition,hierarchical routing hierarchy,scientific spanning tree algorithm,make the OSPF protocol stand out from all kinds of protocols quickly,and become the mainstream of internal gateway protocol together with Intermediate System to Intermediate System(ISIS).The OSPF protocol mainly implements the exchange and forwarding of routes in autonomous regions by sending multicast messages,establishing adjacency relationships,flooding Line State Advertisement(LSA),calculating routes and forwarding.Based on this,the paper mainly explores several common characteristics of OSPF network.
