建立实验拓扑
步骤一、在交换机上建立VLAN
创建与删除
[sw1]vlan 2
[sw1-vlan2]q
[sw1]vlan 3
[sw1-vlan3]q
[sw1]undo vlan 3
批量创建
[sw1]vlan batch 2 to 10
[sw1]display vlan 查看vlan
实操：
步骤二、将交换机上各个接口划分到对应的vlan中
[sw1]interface Eth0/0/1 进入目标端口
[sw1-Ethernet0/0/1]port link-type access 先修改接口模式为接入
[sw1-Ethernet0/0/1]port default vlan 2 定义该接口所在vlan
批量接口划分
[sw1]port-group group-member Ethernet 0/0/3 to Ethernet 0/0/4
[sw1-port-group]port link-type access
[sw1-port-group]port default vlan 3
实操：
步骤三、建立Trunk干道
[sw1]interface Eth0/0/5
[sw1-Ethernet0/0/5]port link-type trunk 先将接口修改为trunk模式
[sw1-Ethernet0/0/5]port trunk allow-pass vlan 2 to 3 再定义该接口允许经过的vlan流量，默认仅允许VLAN1通过
实操：
步骤四:建立单臂路由
[route]interface eth0/0/0.1
[route-Ethernet0/0/0.1]dot1q termination vid 2
[route-Ethernet0/0/0.1]ip address 192.168.1.254 24
[route-Ethernet0/0/0.1]arp broadcast enable
[route-Ethernet0/0/0.1]q
[route]interface Ethernet 0/0/0.2 创建子接口2号
[route-Ethernet0/0/0.2]dot1q termination vid 3 定义其管理和识别vlan id
[route-Ethernet0/0/0.2]ip address 192.168.2.254 24 配置ip地址
[route-Ethernet0/0/0.2]arp broadcast enable
实操：
步骤五、建立DHCP自动为PC端获取IP
[Huawei]dhcp enable
[Huawei]ip pool v2
[Huawei-ip-pool-v2]network 192.168.2.0 mask 24
[Huawei-ip-pool-v2]gateway-list 192.168.2.154
[Huawei-ip-pool-v2]dns-list 114.114.144.144
[Huawei]dhcp enable
[Huawei]ip pool v3
[Huawei-ip-pool-v3]network 192.168.1.0 mask 24
[Huawei-ip-pool-v3]gateway-list 192.168.1.154
[Huawei-ip-pool-v3]dns-list 114.114.144.144
[Huawei]interesting eth0/0/0.1
[Huawei-Ethernet0/0/0.1]dhcp select global
[Huawei-Ethernet0/0/0.1]q
[Huawei]interesting eth0/0/0.2
[Huawei-Ethernet0/0/0.2]dhcp select global
[Huawei-Ethernet0/0/0.2]q
实操：步骤六、验证实验
