9.路由器R1充当DHCP服务器操作步骤    

建地址池塘a

进入系统视图：<r1>sys

改名：[r1]sysname dhcp

启动DHCP服务：[dhcp]dhcp enable

创建地址池塘、并且给这个地址池塘起名称：[dhcp]ip pool a

宣告可以下发地址的范围：[dhcp-ip-pool-a]network 192.168.1.0 mask 24

下发网关的IP地址、不需要跟掩码[dhcp-ip-pool-a]gateway-list 192.168.1.1

下发的DNS服务器的地址[dhcp-ip-pool-a]dns-list 8.8.8.8 114.114.114.114

退出地址池塘进入全局视图：[dhcp-ip-pool-a]q

进入0/0/0接口：[dhcp]interface GigabitEthernet 0/0/0

接口激活DHCP全局的配置：[dhcp-GigabitEthernet0/0/0]dhcp select global

查看地址池塘信息：[dhcp]display ip pool name a

进入0/0/0接口：[dhcp]int GigabitEthernet 0/0/0

查看在这个位置所做的所有指令：[dhcp-GigabitEthernet0/0/0]display this

 

10.路由器R4充当DHCP服务器操作步骤    

建地址池塘b

进入系统视图：<r4>sys

改名：[r4]sysname dhcp

启动DHCP服务：[dhcp]dhcp enable

创建地址池塘、并且给这个地址池塘起名称：[dhcp]ip pool b

宣告可以下发地址的范围：[dhcp-ip-pool-b]network 192.168.6.0 mask 24

下发网关的IP地址、不需要跟掩码[dhcp-ip-pool-b]gateway-list 192.168.6.1

下发的DNS服务器的地址[dhcp-ip-pool-b]dns-list 8.8.8.8 114.114.114.114

退出地址池塘进入全局视图：[dhcp-ip-pool-b]q

进入0/0/1接口：[dhcp]interface GigabitEthernet 0/0/1

接口激活DHCP全局的配置：[dhcp-GigabitEthernet0/0/1]dhcp select global

查看地址池塘信息：[dhcp]display ip pool name b 

进入0/0/1接口：[dhcp]int GigabitEthernet 0/0/1

查看在这个位置所做的所有指令：[dhcp-GigabitEthernet0/0/1]display this
