一、题目要求

要求：
1 、GE0/0/0 口所在广播域使用全局配置模式
2 、 GE0/0/1 口所在广播域使用接口配置模式
3 、租期时间为 1 小时
4 、排除地址池中 IP 在 100 ~200 之间的所有 IP 地址
5 、 IP 网段自行规划，全网可达

二、题目分析

1、在接口0/0/0 中配置dhcp select global

2、在接口0/0/1 中配置dhcp select interface

3、lease day 0 hour 1 minute 0

4、excluded-ip-address 192.168.x.100 192.168.x.200

三、拓扑结构搭建

在这里插入图片描述

接口配置接口0/0/1：


[DHCP Server]dhcp enable
[DHCP Server]int g0/0/1
[DHCP Server-GigabitEthernet0/0/1]ip address 192.168.2.1 24

五、测试验证

PC1,2,3,4被分配了符合规则的ip地址，证明DHCP可用。

PC1:
PC>ipconfig

Link local IPv6 address...........: fe80::5689:98ff:fea8:463b
IPv6 address......................: :: / 128
IPv6 gateway......................: ::
IPv4 address......................: 192.168.1.254
Subnet mask.......................: 255.255.255.0
Gateway...........................: 192.168.1.1
Physical address..................: 54-89-98-A8-46-3B
DNS server........................: 8.8.8.8
  
PC2:
PC>ipconfig

Link local IPv6 address...........: fe80::5689:98ff:fecb:491c
IPv6 address......................: :: / 128
IPv6 gateway......................: ::
IPv4 address......................: 192.168.1.253
Subnet mask.......................: 255.255.255.0
Gateway...........................: 192.168.1.1
Physical address..................: 54-89-98-CB-49-1C
DNS server........................: 8.8.8.8

PC3:
PC>ipconfig

Link local IPv6 address...........: fe80::5689:98ff:fe54:173d
IPv6 address......................: :: / 128
IPv6 gateway......................: ::
IPv4 address......................: 192.168.2.254
Subnet mask.......................: 255.255.255.0
Gateway...........................: 192.168.2.1
Physical address..................: 54-89-98-54-17-3D
DNS server........................: 8.8.8.8


PC4:
PC>ipconfig

Link local IPv6 address...........: fe80::5689:98ff:fea8:4f9c
IPv6 address......................: :: / 128
IPv6 gateway......................: ::
IPv4 address......................: 192.168.2.253
Subnet mask.......................: 255.255.255.0
Gateway...........................: 192.168.2.1
Physical address..................: 54-89-98-A8-4F-9C
DNS server........................: 8.8.8.8

使用PC1 ping PC3可达，证明全网可达。


PC>ipconfig
