拓扑图如下:
配置DHCP中继代理配置
条件如下:
两台AR1220路由器
两台S5700交换机
两台pc(电脑)机
pc1IP地址: 192.168.1.2
pc2IP地址: 192.168.3.2
========================================
两台路由配置命令如下:
AR-1配置:
<Huawei>system-view //进系统视图
[Huawei]sysname AR-1 //修改主机名为:AR-1
[AR-1]int g0/0/0 //进g0/0/0接口
[AR-1-GigabitEthernet0/0/0]ip address 192.168.1.1 24 //配置IP地址和子网掩码
[AR-1-GigabitEthernet0/0/0]int g0/0/1 //切换接口
[AR-1-GigabitEthernet0/0/1]ip address 192.168.2.1 24 //配置IP地址和子网掩码
[AR-1]ip pool p1 //创建地址池p1
[AR-1-ip-pool-p1]network 192.168.1.0 mask 24 //指定网段和掩码
[AR-1-ip-pool-p1]gateway-list 192.168.1.1 //指定网关
[AR-1-ip-pool-p1]ip pool p2 //创建地址池2并切换
[AR-1-ip-pool-p2]network 192.168.3.0 mask 24 //指定网段和掩码
[AR-1-ip-pool-p2]gateway-list 192.168.3.1 //指定网关
[AR-1-ip-pool-p2]q //退到上一层,系统视图
[AR-1]int g0/0/0 //进g0/0/0接口
[AR-1-GigabitEthernet0/0/0]dhcp select global //指定g0/0/0接口为全局模式
[AR-1-GigabitEthernet0/0/0]int g0/0/1 //切换接口
[AR-1-GigabitEthernet0/0/1]dhcp select global //指定g0/0/1接口为全局模式
[AR-1]ip route-static 192.168.3.0 24 192.168.2.2 //指定3网段去往下一条2.2的路由上
====================================================================
检查出的错误:
[AR-1]dhcp enable //开启dhcp服务
[AR-1]int g0/0/1 //进g0/0/1接口
[AR-1-GigabitEthernet0/0/1]dhcp select global //指定g0/0/1接口为全局模式
=======================================================================
AR-2配置:
<Huawei>system-view //进系统视图
[Huawei]sysname AR-2 //修改主机名为:AR-2
[AR-2]int g0/0/1 //进g0/0/1接口
[AR-2-GigabitEthernet0/0/1]ip address 192.168.2.2 24 //配置IP地址和子网掩码
[AR-2-GigabitEthernet0/0/1]int g0/0/0 //切换接口
[AR-2-GigabitEthernet0/0/0]ip address 192.168.3.1 24 //配置IP地址和子网掩码
[AR-2]dhcp enable //开启dhcp服务
[AR-2]int g0/0/1 //进g0/0/1接口
[AR-2]ip route-static 192.168.1.0 24 192.168.2.1 //指定1网段去往下一条的路由上
检查出的错误:
[AR-2]int g0/0/0 //进g0/0/0接口
[AR-2-GigabitEthernet0/0/0]dhcp select relay //指定g0/0/9接口为全局模式
[AR-2-GigabitEthernet0/0/0]dhcp relay server-ip 192.168.2.1 //指定DHCP服务器
