HCIP的OSPF综合实验

一、实验要求

1、R4为ISP，其上只能配置IP地址: R4与其他所有直连设备间使用公有
2、R3—R5/6/7为MGRE环境，R3为中心站点
3、整个OSPF环境IP地址为172.16.0.0/16
4、所有设备均可访问R4的环回
5、减少LSA的更新量，加快收敛，保障更新安全
6、全网可达

二、实验步骤

1.IP地址规划

172.16.0.0/16  
area 0：172.16.0.0/19   
area 1：172.16.32.0/19  
area 2：172.16.64.0/19  
area 3：172.16.96.0/19
area 4：172.16.128.0/19  
rip区域：172.16.160.0/19  

配置缺省路由，使公网全网可达

[R3]ip route-static 0.0.0.0 0 34.1.1.2
[R5]ip route-static 0.0.0.0 0 45.1.1.2
[R6]ip route-static 0.0.0.0 0 46.1.1.2
[R7]ip route-static 0.0.0.0 0 47.1.1.2

 R3—R5/6/7为MGRE环境，R3为中心站点
