OSPF基础介绍

　　　　　　　　　　　　　　　　　　　　　　　　OSPF基础介绍

一.RIP的缺陷

1.以跳数评估的路由并非最优路径

2.最大跳数16导致网络尺度小

3.收敛速度慢

4.更新发送全部路由表浪费网络资源

二.OSPF基本原理

1.什么是OSPF

　　a>.OSPF（Open Shortest Path First,开放最短路径有限）是IETF开发的基于链路状态的自治系统内部路由协议；

　　b>.OSPF仅传播对端设备不具备的路由信息，网络收敛迅速，并有效避免了网络资源浪费；

　　c>.OSPF直接工作于IP层之上，IP协议号为89；

　　d>.OSPF以组播地址发送协议包；

2. OSPF协议工作过程概述

　　a>.寻找邻居；

　　b>.建立邻接关系；

　　注意：上图中的DR和BDR是用来管理一个单区域的，上图中邻接关系数是10，如果都让OSPF来管理是会有很大的负载的，这个时候选举出DR和BDR（DR是管理者，当DR坏掉是有BDR路由器来取得所有权进行管理）来管理这些单区域，多条链路是的话需要选举出来DR和BDR，单挑链路是没有必要选举的，因为没有那么大的负载。　

　　DR和BDR选举

DR,BDR选举规则总结：
　　1>.选举接口优先级，优先级越大越优先，被选DR，优先级第二，被选BDR.
　　2>.如果优先级一样，选route-id,越大优先.
　　3>.如果路由器没有设置route-id，那么选接口的ip地址，越大越优先。

注意：一个单区域中可以没有BDR，但是必须有DR!

c>.链路状态信息传递;

　　d.路由计算

3.OSPF协议分区域管理

4.OSPF协议区域LSA发布

三.配置OSPF

配置下图实验，让公司总部这太电脑能够访问各个机房的主机！
