1.互联IP地址规则：如AR1和AR2互联就是12.1.1.1和12.1.1.2以此类推。
2.环回口配置如AR1? int lo 0 1.1.1.1 32
3.Ospf的routerID跟回环口相同方便记忆。也可以是设备里面没有的IP地址做routeid。只是一个标识。
4.宣告接口注意是只宣告自己有的接口
第一步配置接口IP和回环口地址（IP地址规则如上） ?
第二步配置ospf进程
第三步宣告ospf进程和rip进程
AR1配置回环口和接口IP
[Huawei]int LoopBack 0???????????? //进入回环口0接口（也可以是1接口）
[Huawei-LoopBack0]ip add 1.1.1.1 32? //配置IP地址
[Huawei-LoopBack0]int g0/0/0??????? //直接从回环口进入到接口0
[Huawei-GigabitEthernet0/0/0]ip add 14.1.1.1 24? //配置IP地址
[Huawei-GigabitEthernet0/0/0]int g0/0/2???????? //进入接口2
[Huawei-GigabitEthernet0/0/2]ip add 172.16.10.1 24 ?//配置IP地址（中间有交换机需要三台AR路由器有接口在一个网段）
第二步：配置ospf
[Huawei]ospf 10 router-id 1.1.1.1??? //创建ospf10 配置router-id 为1.1.1.1
[Huawei-ospf-10]area 10?????????? //进入area 10区域
[Huawei-ospf-10-area-0.0.0.10]network 172.16.10.0 0.0.0.255?? //宣告接口网段
[Huawei-ospf-10-area-0.0.0.10]network 14.1.1.0 0.0.0.255? //宣告接口网段
[Huawei-ospf-10-area-0.0.0.10]network 1.1.1.1 0.0.0.0???? //宣告回环口网段
[Huawei-ospf-10-area-0.0.0.10]dis this????????????????? //查看area10下配置的命令
[V200R003C00]
#
?area 0.0.0.10

? network 14.1.1.0 0.0.0.255
? network 172.16.10.0 0.0.0.255
AR2配置回环口和接口IP地址
[Huawei]int LoopBack 0???????????? //进入回环口0接口（也可以是1接口）
[Huawei-LoopBack0]ip add 2.2.2.2 32? //配置IP地址
[Huawei-LoopBack0]int g0/0/0??????? //直接从回环口进入到接口0
[Huawei-GigabitEthernet0/0/0]ip add 172.16.10.2 24 ?//配置IP地址（中间有交换机需要三台AR路由器有接口在一个网段）
第二步：配置ospf
[Huawei]ospf 10 router-id 2.2.2.2??? //创建ospf10 配置router-id 为2.2.2.2
[Huawei-ospf-10]area 10?????????? //进入area 10区域
[Huawei-ospf-10-area-0.0.0.10]network 172.16.10.0 0.0.0.255?? //宣告接口网段
[Huawei-ospf-10-area-0.0.0.10]network 2.2.2.2 0.0.0.0???? //宣告回环口网段
AR3配置回环口和接口IP地址
[Huawei]int LoopBack 0???????????? //进入回环口0接口（也可以是1接口）
[Huawei-LoopBack0]ip add 3.3.3.3 32? //配置IP地址
[Huawei-LoopBack0]int g0/0/0??????? //直接从回环口进入到接口0
[Huawei-GigabitEthernet0/0/0]ip add 172.16.10.3 24 ?//配置IP地址（中间有交换机需要三台AR路由器有接口在一个网段）
第二步：配置ospf
[Huawei]ospf 10 router-id 3.3.3.3??? //创建ospf10 配置router-id 为3.3.3.3
[Huawei-ospf-10]area 10?????????? //进入area 10区域
[Huawei-ospf-10-area-0.0.0.10]network 172.16.10.0 0.0.0.255?? //宣告接口网段
[Huawei-ospf-10-area-0.0.0.10]network 3.3.3.3 0.0.0.0???? //宣告回环口网段
AR4（属于两个区域0和区域10）配置回环口和接口IP地址
[Huawei]int LoopBack 0???????????? //进入回环口0接口（也可以是1接口）
[Huawei-LoopBack0]ip add 4.4.4.4 32? //配置IP地址
[Huawei-LoopBack0]int g0/0/0??????? //直接从回环口进入到接口0
[Huawei-GigabitEthernet0/0/0]ip add 14.1.1.4 24 ?//配置IP地址
[Huawei-GigabitEthernet0/0/0]int g0/0/1??????? //直接从回环口进入到接口1
[Huawei-GigabitEthernet0/0/1]ip add 46.1.1.4 24 ?//配置IP地址
[Huawei-GigabitEthernet0/0/1]int g0/0/2??????? //直接从回环口进入到接口1
[Huawei-GigabitEthernet0/0/2]ip add 45.1.1.4 24 ?//配置IP地址
第二步：配置ospf
[Huawei]ospf 10 router-id 4.4.4.4??? //创建ospf10 配置router-id 为4.4.4.4
[Huawei-ospf-10]area 10?????????? //进入area 10区域
[Huawei-ospf-10-area-0.0.0.10]network 14.1.1..0 0.0.0.255?? //宣告接口网段
[Huawei]ospf 10 router-id 4.4.4.4??? //创建ospf10 配置router-id 为3.3.3.3
[Huawei-ospf-10]area 0? ??????????//进入area 0区域
[Huawei-ospf-10-area-0.0.0.0]network 45.1.1..0 0.0.0.255?? //宣告接口网段
[Huawei-ospf-10-area-0.0.0.0]network 46.1.1..0 0.0.0.255?? //宣告接口网段
