配置DHCP中继功能方法1：适用于小规模DHCP，无需太多繁琐的配置<r1>system-viewdhcpenable//开启DHCPinterfaceGigabitEthernet 0/0/0dhcpselect relay//DHCP选择中继方式dhcprelay server-ip 172.16.23.3//配置DHCP中继服务IP地址（地址为DHCP服务器地址）
方法2：适合于较大规模DHCP，可以卫降低配置量dhcpenable//DHCP功能开启dhcpserver group zurkj//配置DHCP服务组 zurkjdhcp-server172.16.23.3//配置DHCP服务地址quitinterfaceGigabitEthernet 0/0/0dhcpselect relay//配置DHCP选择中继dhcprelay server-select zurkj//配置DHCP中继服务选择zurkj组quit
