[AR-1-ospf-1-area-0.0.0.0]q //退到上一层
[AR-1-ospf-1]area 0.0.0.1 //进入非骨干区域0.0.0.1
[AR-1-ospf-1-area-0.0.0.1]network 192.168.12.0 0.0.0.255 //配置IP地址和反掩码
==================================================================================================

[AR-2-ospf-1-area-0.0.0.1]q //退到上一层
[AR-2-ospf-1]area 0.0.0.2 //进入非骨干区域0.0.0.2
[AR-2-ospf-1-area-0.0.0.2]network 192.168.23.0 0.0.0.255 //配置IP地址和反掩码
===================================================================================================
AR-3配置:
<Huawei>system-view //进系统视图
[Huawei]sysname AR-3 //修改主机名
[AR-3]int g0/0/0 //进g0/0/0接口
[AR-3-GigabitEthernet0/0/0]ip address 192.168.23.3 24 //配置IP地址和子网掩码
启用ospf如下命令
[AR-3]ospf 1 router-id 3.3.3.3 //设置名称为:3.3.3.3
[AR-3-ospf-1]area 0.0.0.2 //进非骨干区域0.0.0.2
[AR-3-ospf-1-area-0.0.0.2]network 192.168.23.0 0.0.0.255 //配置IP地址和反掩码
====================================================================================================
AR-4配置:
<Huawei>system-view //进系统视图
[Huawei]sysname AR-4 //修改主机名
[AR-4]int g0/0/0 //进g0/0/0接口
[AR-4-GigabitEthernet0/0/0]ip address 192.168.14.4 24 //配置IP地址和子网掩码
启用ospf如下命令
[AR-4]ospf 1 router-id 4.4.4.4 //设置名称为 4.4.4.4
[AR-4-ospf-1]area 0.0.0.0 //进入骨干区域0.0.0.0
[AR-4-ospf-1-area-0.0.0.0]network 192.168.14.0 0.0.0.255 //配置IP地址和反掩码
===================================================================================================
穿越区域 1 ，创建虚链路,命令如下:
AR-1配置如下命令：
[AR-1]ospf 1 //进入进程为1的ID
AR-1-ospf-1]area 1 //进入区域1
[AR-1-ospf-1-area-0.0.0.1]vlink-peer 2.2.2.2 //创建虚链路为2.2.2.2
AR-2配置如下命令：
[AR-2]ospf 1 //进入进程为1的ID
[AR-2-ospf-1]area 1 //进入区域1
[AR-2-ospf-1-area-0.0.0.1]vlink-peer 1.1.1.1 //创建虚链路为1.1.1.1
