1、ip地址规划

2、配置ip地址

3、配置ospf

4、让 r1 和 r2 放弃DR和BDR选举

5、保障更新安全

6、对r3进行缺省路由配置

7、测试是否能全网ping的通

8、总结

#### 1、ip地址规划 ####

#### 2、配置ip地址 ####

> r1\]int lo0  
> \[r1-LoopBack0\]ip add 192.168.1.1 27  
> \[r1-LoopBack0\]int g 0/0/0  
> \[r1-GigabitEthernet0/0/0\]ip add 192.168.1.97 27

> \[r2\]int lo0  
> \[r2-LoopBack0\]ip add 192.168.1.33 27  
> \[r2-LoopBack0\]int g 0/0/0  
> \[r2-GigabitEthernet0/0/0\]ip add 192.168.1.98 27

> \[Huawei\]int lo0  
> \[Huawei-LoopBack0\]ip add 192.168.1.65 27  
> \[Huawei-LoopBack0\]int g 0/0/0  
> \[Huawei-GigabitEthernet0/0/0\]ip add 192.168.1.99 27
> 
> \[Huawei-GigabitEthernet0/0/0\]int g 0/0/1  
> \[Huawei-GigabitEthernet0/0/1\]ip add 192.168.1.129 26

> r4\]int lo0  
> \[r4-LoopBack0\]ip add 4.4.4.4 24  
> \[r4-LoopBack0\]int g 0/0/0  
> \[r4-GigabitEthernet0/0/0\]ip add 192.168.1.130 26

#### 3、配置ospf ####

[r4]ospf 1 router-id 4.4.4.4	
    [r4-ospf-1]area 1
    [r4-ospf-1-area-0.0.0.1]network 192.168.1.130 0.0.0.0

#### 4、让 r1 和 r2 放弃DR和BDR选举 ####

> \[r1-GigabitEthernet0/0/0\]ospf dr-priority 0
> 
> \[r2-GigabitEthernet0/0/0\]ospf dr-priority 0

#### 5、保障更新安全 ####

进行接口认证

> \[Huawei-GigabitEthernet0/0/1\]ospf authentication-mode md5 1 cipher 11111

#### 6、对r3进行缺省路由配置 ####

[r3]ip route-static 0.0.0.0 0 192.168.1.130
    [r3]ospf 1
    [r3]ospf 1 router-id 3.3.3.3
    [r3-ospf-1]default-route-advertise

对r3进行汇总

\[r3-ospf-1-area-0.0.0.0\]abr-summary 192.168.1.0 255.255.255.128

对r3设立空接口防止黑洞

\[r3\]ip route-static 192.168.1.0 25 NULL 0

\[r3\]ip route-static 192.168.1.128 25 NULL 0

#### 7、测试是否能全网ping的通 ####
