关于OSPF（二）实验

一、实验目的：
           下面关于OSPF的实验，仔细看配置过程，以增加对OSPF的理解。

二、实现目标：
    使用OSPF实现所有主机之间的通信

三、配置过程：
    1、AR1的配置过程：

    system-view    //进入配置模式
    [Huawei]sysname AR1   //重命名为AR1
    [AR1]interface GigabitEthernet 0/0/0   //进入路由器G0/0/0接口
    [AR1-GigabitEthernet0/0/0]ip address 192.168.0.254 24   //配置接口IP地址
    [AR1-GigabitEthernet0/0/0]interface GigabitEthernet 0/0/1 //进入G0/0/1接口
    [AR1-GigabitEthernet0/0/1]ip address 10.0.1.1 24  //配置IP地址
    [AR1-GigabitEthernet0/0/1]quit
    [AR1]ospf router-id 1.1.1.1   //配置此路由器的router-id为1.1.1.1
    [AR1-ospf-1]area 0    //设置为区域0 （0为主干区域）
    [AR1-ospf-1-area-0.0.0.0]network 192.168.0.0 0.0.0.255 
    [AR1-ospf-1-area-0.0.0.0]network 10.0.1.0 0.0.0.255   //配置路由器两端的网
    //段（网段后填写反掩码:反掩码就是转化为二进制后，1改为0，0改为1）上同
    save
    The current configuration will be written to the device. 
    Are you sure to continue? (y/n)[n]:y
    It will take several minutes to save configuration file, please wait.........

    [AR2-GigabitEthernet0/0/0]interface GigabitEthernet 0/0/1 //进入G0/0/1接口
    [AR2-GigabitEthernet0/0/1]ip address 10.0.1.2 24  //配置IP地址
    [AR2-GigabitEthernet0/0/1]quit
    [AR2]ospf router-id 2.2.2.2   //配置此路由器的router-id为2.2.2.2
    [AR2-ospf-1]area 0    //设置为区域0 （0为主干区域）
    [AR2-ospf-1-area-0.0.0.0]network 192.168.1.0 0.0.0.255 
    [AR2-ospf-1-area-0.0.0.0]network 10.0.1.0 0.0.0.255   //配置路由器两端的网
    //段（网段后填写反掩码:反掩码就是转化为二进制后，1改为0，0改为1）上同
    save
    The current configuration will be written to the device.
