vlan虚拟子接口

1.搭建虚拟子接口拓扑图

2.建立VLAN接入接口

[Huawei]vlan 2
[Huawei]interface e0/0/2
[Huawei-Ethernet0/0/2]port link-type access
[Huawei-Ethernet0/0/2]port default vlan 2


 3.划分虚拟子接口

[Huawei]interface g0/0/0.1
[Huawei-GigabitEthernet0/0/0.1]dot1q termination vid 2
[Huawei-GigabitEthernet0/0/0.1]ip address 12.1.1.1 24

4.建立DHCP池分配IP地址

[Huawei]ip pool 1
[Huawei-ip-pool-1]network 12.1.1.0 mask 255.255.255.0
[Huawei-ip-pool-1]gateway-list 12.1.1.1
[Huawei-ip-pool-1]dns-list 8.8.8.8
[Huawei-GigabitEthernet0/0/0.1]dhcp select global
[Huawei-GigabitEthernet0/0/0.1]arp broadcast enable
[Huawei-GigabitEthernet0/0/0.1]quit

5.IP地址自动发放全网可达
