创建拓扑

先配置AR2

[Huawei]dhcp enable 开启DHCP

[Huawei]int g 0/0/1.1 进入子接口

[Huawei-GigabitEthernet0/0/1.1]dot1q terminatio vid 10 处理vlan 10报文

[Huawei-GigabitEthernet0/0/1.1]arp broadcast enable 开启接口处理arp广播报文

[Huawei-GigabitEthernet0/0/1.1]ip add 192.168.1.1 24 配置子接口ip

[Huawei-GigabitEthernet0/0/1.1]dhcp select global 选择全局地址池

[Huawei-ip-pool-vlan10]ip pool vlan10 创建地址池

[Huawei-ip-pool-vlan10]gateway-list 192.168.1.1 下发的网关（需要与子接口ip一致）

[Huawei-ip-pool-vlan10]network 192.168.1.0 mask 24 下发的网段及其子网掩码

[Huawei-ip-pool-vlan10]quit [Huawei]int g 0/0/1.2

[Huawei-GigabitEthernet0/0/1.2]dot1q terminatio vid 20

[Huawei-GigabitEthernet0/0/1.2]ip add 192.168.10.1 24

[Huawei-GigabitEthernet0/0/1.2]arp broadcast enable

[Huawei-GigabitEthernet0/0/1.2]dhcp select global

[Huawei-GigabitEthernet0/0/1.2]ip pool vlan20

[Huawei-ip-pool-vlan20]network 192.168.10.0 mask 24

[Huawei-ip-pool-vlan20]gateway-list 192.168.10.1

[Huawei-ip-pool-vlan20]

配置LSW1

vlan batch 10 20 创建vlan 10 和 vlan 20

interface GigabitEthernet0/0/1

port link-type trunk 接口模式改为trunk

port trunk allow-pass vlan 10 20 允许vlan 10,20通过

interface GigabitEthernet0/0/2

port link-type access

port default vlan 10

interface GigabitEthernet0/0/3

port link-type access p

ort default vlan 20

配置pc

验证是否成功
