1、打开eNSP模拟器，新建拓扑，添加一台路由器，一台交换机，两台PC电脑，连线使用接口如图
3、继续在LSW1控制台输入命令创建vlan 3并分配端口：[Huawei]vlan 3[Huawei-vlan3]quit[Huawei]inter GigabitEthernet 0/0/3[Huawei-GigabitEthernet0/0/3]port link-type access[Huawei-GigabitEthernet0/0/3]port default vlan 3[Huawei-GigabitEthernet0/0/3]
5、启动路由器，进入CLI控制台在路由器物理端口GigabitEthernet0/0/0虚拟两个端口对应两个vlan,命令如下：<Huawei>system-viewEnter system view, return user view with Ctrl+Z.[Huawei]inter gi 0/0/0.1[Huawei-GigabitEthernet0/0/0.1]dot1q termination vid 2[Huawei-GigabitEthernet0/0/0.1]ip address 10.5.1.254 255.255.255.0[Huawei-GigabitEthernet0/0/0.1]arp broadcast enable[Huawei-GigabitEthernet0/0/0.1]quit[Huawei]inter gi 0/0/0.2[Huawei-GigabitEthernet0/0/0.2]dot1q termination vid 3[Huawei-GigabitEthernet0/0/0.2]ip address 10.5.2.254 255.255.255.0[Huawei-GigabitEthernet0/0/0.2]arp broadcast enable
7、配置PC2的ip如下图，注意网关要配成路由器封装vlan 3的ip address
