0x3 HCNP-R&S OSPF单区域作业（华为eNSP）

要求：

1，给所有设备配置正确地址
2，全网启用单区域ospf路由协议，使全网互通
3, 每个路由器使用loopback接口地址作为自己的router id
4，在192.168.1.0网段使AR6成为DR，AR7成为BDR，并通过命令能查看到

拓扑结构：

路由器配置

1、各路由器端口、回环口进行IP分配

AR6

2、OSPF DR/BDR选举手工控制

注意点：需要各个路由器在接口处配置

AR6

[AR6]interface GigabitEthernet 0/0/0
[AR6-GigabitEthernet0/0/0]ospf dr-priority 100

AR7

[AR7]interface GigabitEthernet 0/0/0
[AR7-GigabitEthernet0/0/0]ospf dr-priority 80

AR8

[AR8]interface GigabitEthernet 0/0/0
[AR8-GigabitEthernet0/0/0]ospf dr-priority 50

AR9

[AR9]interface GigabitEthernet 0/0/0
[AR9-GigabitEthernet0/0/0]ospf dr-priority 30

3、验证 各个路由输入

display ospf peer//查看OSPF邻居

 

 

 

做完实验之后记得各个路由器save

save
  The current configuration will be written to the device. 
  Are you sure to continue? (y/n)[n]:y//这里选择y
  It will take several minutes to save configuration file, please wait.......
  Configuration file had been saved successfully
  Note: The configuration file will take effect after being activated
