【eNSP实战】将路由器配置为DHCP服务器

拓图

要求：

1. 为 office100 和 office200 分别配置地址池

AR1接口配置

interface GigabitEthernet0/0/0ip address 192.168.100.1 255.255.255.0 
#
interface GigabitEthernet0/0/1ip address 192.168.200.1 255.255.255.0 

AR1路由器上创建office100地址池

[AR1]dhcp enable 		# 全局开启DHCP服务
[AR1]ip pool office100	# 创建office100地址池（名称随意）
[AR1-ip-pool-office100]network 192.168.100.0 mask 24	# 指定地址池所在网段
[AR1-ip-pool-office100]gateway-list 192.168.100.1		# 指定该网段的网关
[AR1-ip-pool-office100]dns-list 8.8.8.8 			# 指定DNS服务器
[AR1-ip-pool-office100]dns-list 114.114.114.114		# 指定第二个DNS服务器
[AR1-ip-pool-office100]lease day 0 hour 8 minute 0 	# 地址租约，允许客户端使用8小时
[AR1-ip-pool-office100]excluded-ip-address 192.168.100.2 192.168.100.10		# 指定排除的地址范围（不能包括网关地址）
[AR1-ip-pool-office100]quit

AR1路由器上，配置接口从地址池获取地址

[AR1]interface GigabitEthernet 0/0/0
[AR1-GigabitEthernet0/0/0]dhcp select global 
[AR1-GigabitEthernet0/0/0]quit

至此office100地址池配置完成，下面开始配置office200地址池
AR1上创建office200地址池，并配置接口从地址池获取地址

[AR1]ip pool office200	
[AR1-ip-pool-office200]network 192.168.200.0 mask 24
[AR1-ip-pool-office200]gateway-list 192.168.200.1
[AR1-ip-pool-office200]dns-list 8.8.8.8
[AR1-ip-pool-office200]dns-list 223.5.5.5
[AR1-ip-pool-office200]lease day 0 hour 8 minute 0
[AR1-ip-pool-office200]excluded-ip-address 192.168.200.2 192.168.200.10
[AR1-ip-pool-office200]quit
[AR1]interface GigabitEthernet 0/0/1
[AR1-GigabitEthernet0/0/1]dhcp select global 
[AR1-GigabitEthernet0/0/1]quit

至此DHCP全部配置完成，下面查看pc自动获取IP情况
