DHCP实验

DHCP实验

拓扑图

实验要求：

1. 全网互通，主机通过DHCP获取ip地址
2. 要求如图

实验配置

• pc开启DHCP，修改设备名，网络设备配置ip地址，使用静态路由实现全网互通

略

• 开启dhcp服务，创建dhcp地址池，并按照如图上配置

[dhcp-server]dhcp enable

[dhcp-server]dhcp server ip-pool 1

[dhcp-server-dhcp-pool-1]network 172.168.1.0 24

[dhcp-server-dhcp-pool-1]gateway-list 172.168.1.2

[dhcp-server-dhcp-pool-1]dns-list 1.1.1.1

[dhcp-server-dhcp-pool-1]expired day 2

[dhcp-server-dhcp-pool-1]forbidden-ip 172.168.1.128 172.168.1.168 172.168.1.2

[dhcp-server-dhcp-pool-1]forbidden-ip-range 172.168.1.180 172.168.1.200

• dhcp relay设备开启dhcp服务，在需要分配ip地址网段的接口上配置dhcp服务器的ip地址以及选则relay

[dhcp-relay]dhcp enable

[dhcp-relay-GigabitEthernet0/1]dhcp relay server-address 172.168.2.1

[dhcp-relay-GigabitEthernet0/1]dhcp select relay

• 查看PC是否都获取到了ip地址

• 在dhcp-server上配置地址池2，给PC3提供dhcp服务

[dhcp-server]dhcp server ip-pool 2

[dhcp-server-dhcp-pool-2] gateway-list 172.168.3.1

[dhcp-server-dhcp-pool-2] network 172.168.3.0 mask 255.255.255.0

最终PC3成功获取到ip地址
