OSPF虚链路实验

一.实验环境

实验环境：gns3，c6291路由器

三.实验步骤

我们先将R1的ip配置好。<img src="https://cache.tdyun.com/upload/information/20200309/33/53290.jpg" alt="mark" style="zoom:75%;" />

然后配置ospf协议和分配area。<img src="https://cache.tdyun.com/upload/information/20200309/33/53291.jpg" alt="mark" style="zoom:75%;" />

然后对R2设置ip<img src="https://cache.tdyun.com/upload/information/20200309/33/53292.jpg" alt="mark" style="zoom:75%;" />

配置ospf协议和分配area<img src="https://cache.tdyun.com/upload/information/20200309/33/53293.jpg" alt="mark" style="zoom:75%;" />

同样的步骤对R3操作<img src="https://cache.tdyun.com/upload/information/20200309/33/53294.jpg" alt="mark" style="zoom:75%;" />

R4也是如此。<img src="https://cache.tdyun.com/upload/information/20200309/33/53296.jpg" alt="mark" style="zoom:75%;" />

最后我们还得给R2和R3加虚链路。R2操作如图<img src="https://cache.tdyun.com/upload/information/20200309/33/53298.jpg" alt="mark" style="zoom:75%;" />

R3如图<img src="https://cache.tdyun.com/upload/information/20200309/33/53299.jpg" alt="mark" style="zoom:75%;" />

pc机的ip地址自配。至此，实验结束，可以尝试是否可以ping成功。
