实验要求:
1.如图连接,合理规划IP地址,所有路由器各自创建一个loopback接口
2.R1再创建三个接口IP地址为201.1.1.1/24、201.1.2.1/24、201.1.3.1/24
R5再创建三个接口IP地址为202.1.1.1/24、202.1.2.1/24、202.1.3.1/24
R7再创建三个接口IP地址为203.1.1.1/24、203.1.2.1/24、203.1.3.1/24
3.如图运行路由协议
R1 -R2 -R3之间使用MGRE网络,为hub-spoke 网络结构,R1为hub端 ,
部署OSPF网络,MGRE修改为BMA网络类型
4.area 1 区域不得出现4.5类LSA
5.其他区域优先通过R3访问R1 三个环回接口
6.尽量减少路由条目数量
7.area 1 区域增加安全性
8.全网可达
一、拓扑如图:
二、各个路由器进行接口配置:
