## 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**

<Huawei>system-view 
    [Huawei]sysname AR6
    [AR6]interface LoopBack 0
    [AR6-LoopBack0]ip address 5.5.5.5 32
    [AR6-LoopBack0]quit
    [AR6]interface GigabitEthernet0/0/0	
    [AR6-GigabitEthernet0/0/0]ip address 192.168.1.1 24
    [AR6-GigabitEthernet0/0/0]quit
    [AR6]router id 5.5.5.5
    [AR6]ospf                 	
    [AR6-ospf-1-area-0.0.0.0]network 192.168.1.0 0.0.0.255
    [AR6-ospf-1-area-0.0.0.0]network 5.5.5.5 0.0.0.0

**AR7**

<Huawei>system-view 
    [Huawei]sysname AR7
    [AR7]interface LoopBack 0
    [AR7-LoopBack0]ip address 4.4.4.4 32
    [AR7-LoopBack0]quit
    [AR7]interface GigabitEthernet0/0/0	
    [AR7-GigabitEthernet0/0/0]ip address 192.168.1.2 24
    [AR7-GigabitEthernet0/0/0]quit
    [AR7]router id 4.4.4.4
    [AR7]ospf
    [AR7-ospf-1]area 0                 	
    [AR7-ospf-1-area-0.0.0.0]network 192.168.1.0 0.0.0.255
    [AR7-ospf-1-area-0.0.0.0]network 4.4.4.4 0.0.0.0

**AR8**

<Huawei>system-view 
    [Huawei]sysname AR8
    [AR8]interface LoopBack 0
    [AR8-LoopBack0]ip address 3.3.3.3 32
    [AR8-LoopBack0]qu
    [AR8]interface g0/0/0	
    [AR8-GigabitEthernet0/0/0]ip address 192.168.1.3 24 
    [AR8-GigabitEthernet0/0/0]qu
    [AR8]router id 3.3.3.3
    [AR8]ospf
    [AR8-ospf-1]area 0
    [AR8-ospf-1-area-0.0.0.0]network 192.168.1.0 0.0.0.255
    [AR8-ospf-1-area-0.0.0.0]network 3.3.3.3 0.0.0.0

**AR9**

<Huawei>system-view 
    [Huawei]sysname AR9
    [AR9]interface LoopBack 0
    [AR9-LoopBack0]ip address 2.2.2.2 32
    [AR9-LoopBack0]qu
    [AR9]interface g0/0/0
    [AR9-GigabitEthernet0/0/0]ip address 192.168.1.4 24
    [AR9-GigabitEthernet0/0/0]qu
    [AR9]router id 2.2.2.2
    [AR9]ospf
    [AR9-ospf-1]area 0
    [AR9-ospf-1-area-0.0.0.0]net	
    [AR9-ospf-1-area-0.0.0.0]network 192.168.1.0 0.0.0.255
    [AR9-ospf-1-area-0.0.0.0]network 2.2.2.2 0.0.0.0

### 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

![70 1][]

![70 2][]

![70 3][]

![70 4][]

做完实验之后记得各个路由器save

<Huawei>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
