cisco_ospf路由重分布和虚链路的配置

时间：2024-03-10 08:49:15

需求：

1、R1、R2、R3、R4的f0/0接口分别配置100.1.1.1-4并启动ospf路由协议加入area 0

2、R1、R2、R3、R4分别配置回环接口1.1.1.1、2.2.2.2、3.3.3.3、4.4.4.4；分别加入area 1、area 2、area 3、area 4

3、R2的f0/1和R5的f0/0接口改为p2p，不选举DR/BDR

4、R5和R6上配置rip协议，在R5上配置路由重分布

5、在R3和R7上配置静态路由，在R3上配置路由重分布

6、在R4和R8之间配置虚链路，使R9可以学习area 0里的路由
