DHCP DHCP中继

DHCP SERVER:

cisco（config）#int f0/0

cisco（config-if）#ip address 192.168.1.1

cisco（config-if）#no shutdown

cisco（config-if）#exit

 

cisco（config）#ip dhcp exclude-address 192.168.1.1 192.168.1.10

cisco（config）#ip dhcp pool ccnp

cisco（dhcp-config）#network 192.168.1.0 /24

cisco（dhcp-config）#default-router 192.168.1.1

cisco（dhcp-config）#dns-server 202.102.224.68

cisco（dhcp-config）#lease 3            (days)

cisco（dhcp-config）#exit

cisco（config）#exit

cisco#show ip dhcp binding

 

路由器接口开启DHCP Client：

cisco（config-if）#ip address dhcp

 

DHCP 中继：

cisco（config）#int f0/0                                            （为连接以太网接口）

cisco（config-if）#ip helper-address 192.168.2.2  （192.168.2.2为DHCP SERVER IP）
