本章目的：全网互通，R2设置静态路由，R2和R3在AREA1区域中使用OSPF协议，R3设置默认路由回来，R4和R5使用RIP协议

本章环境：GNS3,5台路由器，4台主机，1个外部网.

实验图：

R3的路由器要多加一块单板

1.配置R1路由器

2.配置R2路由器接口地址

3.配置R2静态路由和OSPF协议

4.配置R3接口地址

5.配置R3默认路由和OSPF协议

6.配置R4接口地址

7.配置R4RIP协议，注入OSPF协议

8.配置R6接口地址

9.配置R6RIP协议

10.配置R5外部网默认路由，和接口地址

11.给四台主机配好地址

12.验证一下是不是全网互通

以上就是我们的综合实验了，下一章OSPF最后一个实验虚链路。
