实验拓扑图

1、配置PC的IP地址：

PC1

PC2

PC3

2、配置交换机：创建VLAN 10 20 30 ，把与PC相连的接口划入对应的VLAN，更改接口模式， 把交换机GE0/0/1改为trunk，并允许通过VLAN 10 20 30。配置如下：

system-view

[Huawei]sysname S1

[S1]vlan batch 10 20 30 //创建VLAN 10 20 30

[S1]interface GigabitEthernet 0/0/2

[S1-GigabitEthernet0/0/2]port link-type access

[S1-GigabitEthernet0/0/2]port default vlan 10

[S1-GigabitEthernet0/0/2]interface GigabitEthernet 0/0/3

[S1-GigabitEthernet0/0/3]port link-type access

[S1-GigabitEthernet0/0/3]port default vlan 20

[S1-GigabitEthernet0/0/3]interface GigabitEthernet 0/0/4

[S1-GigabitEthernet0/0/4]port link-type access

[S1-GigabitEthernet0/0/4]port default vlan 30

[S1]interface GigabitEthernet 0/0/1

[S1-GigabitEthernet0/0/1]port link-type trunk

[S1-GigabitEthernet0/0/1]port trunk allow-pass vlan all

AR1配置：

system-view

[Huawei]sysname AR1

[AR1]interface GigabitEthernet 0/0/0.1

[AR1-GigabitEthernet0/0/0.1]ip address 192.168.1.254 24

[AR1-GigabitEthernet0/0/0.1]dot1q termination vid 10 //VLAN10打标签

[AR1-GigabitEthernet0/0/0.1]arp broadcast enable

[AR1-GigabitEthernet0/0/0.1]interface GigabitEthernet 0/0/0.2

[AR1-GigabitEthernet0/0/0.2]ip address 192.168.2.254 24

[AR1-GigabitEthernet0/0/0.2]dot1q termination vid 20 //VLAN20打标签

[AR1-GigabitEthernet0/0/0.2]arp broadcast enable

[AR1-GigabitEthernet0/0/0.2]interface GigabitEthernet 0/0/0.3

[AR1-GigabitEthernet0/0/0.3]ip address 192.168.3.254 24

[AR1-GigabitEthernet0/0/0.3]dot1q termination vid 30 //打VLAN30标签

[AR1-GigabitEthernet0/0/0.3]arp broadcast enable
