1）配置OSPF实现全网互通。

2）使用命令验证配置。

搭建实验环境：
在这里插入图片描述

现此案例需要按照如下步骤进行。

//R1的配置
 ospf 1 router-id 1.1.1.1
       area 0 
         network 192.168.10.0 0.0.0.255
         network 192.168.1.1 0.0.0.0
      network 192.168.21.0 0.0.0.3
//R2的配置
  ospf 1 router-id 2.2.2.2
        area 0 
          network 192.168.21.0 0.0.0.3
network 192.168.23.0 0.0.0.3
network 192.168.2.1 0.0.0.0
//R3的配置
  ospf 1 router-id 3.3.3.3
        area 0 
          network 192.168.23.0 0.0.0.3
          network 192.168.30.0 0.0.0.255
network 192.168.3.1 0.0.0.0

能够全网ping通。
