在两台二层交换机上创建vlan【sw1?vlan10 sw2?vlan20】并将三个端口加入相应的vlan中 [sw1]vlan 10 [sw1-vlan10]q [sw1-GigabitEthernet0/0/1]undo sh Info: Interface GigabitEthernet0/0/1 is not shutdown. [sw1-Ethernet0/0/1]port link-type acc//选择access模式 [sw1-Ethernet0/0/1]port def vlan 10 //加入vlan10 其他端口同理【sw2上只是把vlan10换成vlan20】
配置三层交换机： 创建vlan10、2 将vlan10/20加入端口【access模式】 配置vlanIP： [dhcp-Vlanif10]undo sh Info: Interface Vlanif10 is not shutdown. [dhcp-Vlanif10] [dhcp-Vlanif10] [dhcp-Vlanif10]ip add 192.168.10.254 255.255.255.0 [dhcp-Vlanif20]ip add 192.168.20.254 255.255.255.0 创建地址池: [dhcp]ip pool vlan-10 Info:It‘s successful to create an IP address pool.

Please wait for a moment.done. [dhcp-Vlanif10]dhcp select global [dhcp-Vlanif20]dhcp select global 配置完成 3.验证、测试、保存 实验拓扑图：
