1、构建网络拓扑图
2、先配置路由器R1的各接口ip，然后再配置ospf协议，具体配置命令如下：
<Huawei>
<Huawei>sys / system view命令的简写，进入系统视图
Enter system view, return user view with Ctrl+Z.
[Huawei]un in en /此命令是undo info-center enable的简写，这个命令关闭信息中心功能，这样做配置的过程中，就不会再出现那种告警信息了。
Info: Information center is disabled.
[Huawei]sysn R1 /sysn是 sysname的简写，修改设备名称
/配置R1各接口ip
[R1]int g0/0/1 /此命令是interface gigabitethernet 0/0/1的简写，进入路由器接口视图
[R1-GigabitEthernet0/0/1]ip add 192.168.1.1 24 //add是address的简写
[R1-GigabitEthernet0/0/1]int g0/0/2
[R1-GigabitEthernet0/0/2]ip add 192.168.2.1 24
[R1-GigabitEthernet0/0/2]quit
/在路由器R1上配置OSPF基本功能
[R1]ospf
[R1-ospf-1]area 0
[R1-ospf-1-area-0.0.0.0]net 192.168.1.0 0.0.0.255
[R1-ospf-1-area-0.0.0.0]quit
[R1-ospf-1]area 1
[R1-ospf-1-area-0.0.0.1]net 192.168.2.0 0.0.0.255
[R1-ospf-1-area-0.0.0.1]quit
[R1-ospf-1]quit
[R1]dis ip routing /查看路由表信息
3、路由器R2，R3，R4，R5，R6，的配置过程与R1类似：
R2：
<Huawei>
<Huawei>sys
Enter system view, return user view with Ctrl+Z.
[Huawei]un in en
Info: Information center is disabled.
[Huawei]sysn R2
[R2]int g0/0/1
[R2-GigabitEthernet0/0/1]ip add 192.168.1.2 24
[R2-GigabitEthernet0/0/1]int g0/0/2
[R2-GigabitEthernet0/0/2]ip add 192.168.4.1 24
[R2-GigabitEthernet0/0/2]quit
[R2]ospf
[R2-ospf-1]area 0
[R2-ospf-1-area-0.0.0.0]net 192.168.1.0 0.0.0.255
[R2-ospf-1-area-0.0.0.0]quit
[R2-ospf-1]area 2
[R2-ospf-1-area-0.0.0.2]net 192.168.4.0 0.0.0.255
[R2-ospf-1-area-0.0.0.2]quit
[R2-ospf-1]quit
[R2]quit
<R2>dis ip routing
R3：
<Huawei>
<Huawei>sys
Enter system view, return user view with Ctrl+Z.
[Huawei]un in en
Info: Information center is disabled.
[Huawei]sysn R3
[R3]int g0/0/1
[R3-GigabitEthernet0/0/1]ip add 192.168.2.2 24
[R3-GigabitEthernet0/0/1]int g0/0/2
[R3-GigabitEthernet0/0/2]ip add 192.168.3.1 24
[R3-GigabitEthernet0/0/2]quit
[R3]ospf
[R3-ospf-1]area 1
[R3-ospf-1-area-0.0.0.1]net 192.168.2.0 0.0.0.255
[R3-ospf-1-area-0.0.0.1]net 192.168.3.0 0.0.0.255
[R3-ospf-1-area-0.0.0.1]quit
[R3-ospf-1]quit
[R3]dis ip routing
R4：
<Huawei>
<Huawei>sys
Enter system view, return user view with Ctrl+Z.
[Huawei]un in en
Info: Information center is disabled.
[Huawei]sysn R4
[R4]int g0/0/1
[R4-GigabitEthernet0/0/1]ip add 192.168.4.2 24
[R4-GigabitEthernet0/0/1]int g0/0/2
[R4-GigabitEthernet0/0/2]ip add 192.168.5.1 24
[R4]ospf
[R4-ospf-1]area 2
[R4-ospf-1-area-0.0.0.2]net 192.168.4.0 0.0.0.255
[R4-ospf-1-area-0.0.0.2]net 192.168.5.0 0.0.0.255
[R4-ospf-1-area-0.0.0.2]quit
[R4-ospf-1]quit
[R4]dis ip routing
R5：
<Huawei>
<Huawei>sys
Enter system view, return user view with Ctrl+Z.
[Huawei]un in en
Info: Information center is disabled.
[Huawei]sysn R5
[R5]int g0/0/1
[R5-GigabitEthernet0/0/1]ip add 192.168.3.2 24
[R5]ospf
[R5-ospf-1]area 1
[R5-ospf-1-area-0.0.0.1]net 192.168.3.0 0.0.0.255
[R5-ospf-1-area-0.0.0.1]quit
[R5-ospf-1]quit
[R5]dis ip routing
R6：
<Huawei>
<Huawei>sys
Enter system view, return user view with Ctrl+Z.
[Huawei]un in en
Info: Information center is disabled.
[Huawei]sysn R6
[R6]int g0/0/1
[R6-GigabitEthernet0/0/1]ip add 192.168.5.2 24
[R6]ospf
[R6-ospf-1]area 2
[R6-ospf-1-area-0.0.0.2]net 192.168.5.0 0.0.0.255
[R6-ospf-1-area-0.0.0.2]quit
[R6-ospf-1]quit
[R6]dis ip routing
4、配置完成后，在路由器上使用dis ip routing，查看配置结果，R1，R2，R3的结果如图所示。
5、在路由器上使用dis ospf routing，查看ospf的信息，R1，R2，R3的结果如图所示。
