如图第一步首先在R4与R6上设置互联地址并且R4向R6配置静态路由ip route-static 192.168.1.0 255.255.255.0 10.1.1.2。第二步在R4上创建地址池ip pool DhcpTestgateway-list 192.168.1.1network 192.168.1.0 mask 255.255.255.0dns-list 8.8.8.8第三步两台路由器全局开启DHCP enable。第四步R4接口配置interface GigabitEthernet0/0/0ip address 10.1.1.1 255.255.255.252dhcp select global# 第五步R6接口配置interface GigabitEthernet0/0/1ip address 192.168.1.1 255.255.255.0dhcp select relaydhcp relay server-ip 10.1.1.1第六步PC获取到地址完毕
