网络工程实验三：DHCP的配置

#实验仅供参考，勿直接粘贴复制，用以学习交流#

#对于软件的使用，请移步到实验一观看#

1、实验目的：

（1）掌握DHCP工作原理。

（2）配置路由器作为DHCP服务器。

（3）配置DHCP中继实现跨网段地址自动配置。

2、实验图像绘制与相应基础配置

绘制本次实验的图像如下所示：

配置路由器AR1,AR2的各接口的地址，如下所示：

AR1:

复制代码

<Huawei>sys 
[Huawei]sysname AR1
[AR1]interface GigabitEthernet 0/0/0 
[AR1-GigabitEthernet0/0/0]ip address 192.168.0.1 24 
[AR1-GigabitEthernet0/0/0]quit 
[AR1]interface GigabitEthernet 0/0/1 
[AR1-GigabitEthernet0/0/1]ip address 192.168.1.1 24 
[AR1]interface GigabitEthernet 1/0/0 
[AR1-GigabitEthernet0/0/1]ip address 172.16.0.1 24 
[AR1-GigabitEthernet0/0/1]quit 
[AR1]display ip interface brief   //用于显示结果自己检查端口IP是否正确

AR2:

复制代码

<Huawei>sys 
[Huawei]sysname AR2 
[AR2]interface GigabitEthernet 0/0/0 
[AR2-GigabitEthernet0/0/0]ip address 172.16.0.2 24 
[AR2-GigabitEthernet0/0/0]quit 
[AR2]interface GigabitEthernet 0/0/1 
[AR2-GigabitEthernet0/0/1]ip address 192.168.3.1 24 
[AR2-GigabitEthernet0/0/1]quit 
[AR2]display ip interface brief    //用于显示结果自己检查端口IP是否正确

3、配置静态路由，使得PC1和PC2能够通信

配置后的AR1,AR2静态路由器表和代码如下所示：

AR1:

复制代码

<AR1>sys
[AR1]ip route-static 192.168.3.0 24 172.16.0.2 
[AR1]display ip routing-table protocol static   //显示静态路由器表，用于自查

AR2:

复制代码

<AR2>sys
[AR2]ip route-static 192.168.0.0 24 172.16.0.1 
[AR2]ip route-static 192.168.1.0 24 172.16.0.1 
[AR2]display ip routing-table protocol static   //显示静态路由器表，用于自查

4、DHCP配置：

对于office1进行部分地址池配置，分配给PC1的地址

复制代码

[AR1]dhcp enable 
[AR1]ip pool office1 
[AR1-ip-pool-office1]network 192.168.0.0 mask 24
[AR1-ip-pool-office1]gateway-list 192.168.0.1
[AR1-ip-pool-office1]dns-list 8.8.8.8
[AR1-ip-pool-office1]lease day 0 hour 8 minute 0
[AR1-ip-pool-office1]excluded-ip-address 192.168.0.50 192.168.0.60
[AR1-ip-pool-office1]display this
[AR1-ip-pool-office1]quit
[AR1]interface GigabitEthernet 0/0/0
[AR1-GigabitEthernet0/0/0]dhcp select global

对于office2进行部分接口地址池配置，分配给PC2的地址

复制代码

[AR1]interface GigabitEthernet 0/0/1
[AR1-GigabitEthernet0/0/1]dhcp select interface 
[AR1-GigabitEthernet0/0/1]dhcp server dns-list 8.8.8.8
[AR1-GigabitEthernet0/0/1]dhcp server lease day 1 hour 0 minute 0
[AR1-GigabitEthernet0/0/1]dhcp server excluded-ip-address 192.168.1.50 192.168.1.60
[AR1-GigabitEthernet0/0/1]quit

对于office3部分使用中继与地址池配置，分配给PC3的地址

复制代码

[AR1]ip pool office3
[AR1-ip-pool-office3]network 192.168.3.0 mask 24
[AR1-ip-pool-office3]gateway-list 192.168.3.1
[AR1-ip-pool-office3]dns-list 8.8.8.8
[AR1-ip-pool-office3]quit
[AR1]interface GigabitEthernet 1/0/0
[AR1-GigabitEthernet1/0/0]dhcp select global
[AR1-GigabitEthernet1/0/0]quit

[AR2]dhcp enable
[AR2]interface GigabitEthernet 0/0/1
[AR2-GigabitEthernet0/0/1]dhcp select relay
[AR2-GigabitEthernet0/0/1]dhcp relay server-ip 172.16.0.1
[AR2-GigabitEthernet0/0/1]quit

#本实验使用三种配置方式，分别为部分地址池配置、使用接口地址池配置和使用中继与地址池配置，仅供参考，实际应用时应考虑所使用的环境#
