要求：

1. 為 office100 和 office200 分別配置地址池

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路由器上創建office100地址池

[AR1]dhcp enable 		# 全局開啟DHCP服務
[AR1]ip pool office100	# 創建office100地址池（名稱隨意）
[AR1-ip-pool-office100]network 192.168.100.0 mask 24	# 指定地址池所在網段
[AR1-ip-pool-office100]gateway-list 192.168.100.1		# 指定該網段的網關
[AR1-ip-pool-office100]dns-list 8.8.8.8 			# 指定DNS服務器
[AR1-ip-pool-office100]dns-list 114.114.114.114		# 指定第二個DNS服務器
[AR1-ip-pool-office100]lease day 0 hour 8 minute 0 	# 地址租約，允許客戶端使用8小時
[AR1-ip-pool-office100]excluded-ip-address 192.168.100.2 192.168.100.10		# 指定排除的地址范圍（不能包括網關地址）
[AR1-ip-pool-office100]quit

AR1路由器上，配置接口從地址池獲取地址

[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，下面開始配置office200地址池
AR1上創建office200地址池，并配置接口從地址池獲取地址

[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自動獲取IP情況
