一：实验要求：要使得VLAN10的PC1与VLAN20的PC2能PING通
二：所需设备：一台AR1220路由器，一台S3700交换机，两台PC机
三：实验拓扑：
四：实验步骤
1.开启所有设备
2.给LSW1更改主机名为sw1
<Huawei>SYS
[Huawei]sysname sw1
[sw1]
2.给LSW1添加VLAN10 和 VLAN 20
<sw1>SYS //用户模式
[sw1]VLAN 10 //在特权模式下新建VLAN10
[sw1-vlan10] //进入VLAN10
[sw1-vlan10]VLAN 20 //新建VLAN20
[sw1-vlan20] //进入VLAN20
3.在LSW1中将PC1加入VLAN 10 PC2加入VLAN 20
[sw1-vlan20]int e0/0/2
[sw1-Ethernet0/0/2]port link-type access
[sw1-Ethernet0/0/2]port default vlan 10
[sw1-Ethernet0/0/2]int e0/0/3
[sw1-Ethernet0/0/3]port link-type access
[sw1-Ethernet0/0/3]port default vlan 20
[sw1-Ethernet0/0/3]
查看VLAN10 VLAN20
[sw1-Ethernet0/0/3]dis vlan
反馈信息的一部分：
-----------------------------------------------------------------1 common UT:Eth0/0/1(U) Eth0/0/4(D) Eth0/0/5(D) 10 common UT:Eth0/0/2(U)
20 common UT:Eth0/0/3(U)
4.将GE0/0/1接口改成中继口
[sw1]int g0/0/1
[sw1-GigabitEthernet0/0/1]port link-type trunk
[sw1-GigabitEthernet0/0/1]port trunk allow-pass vlan all
5.在AR1中建立子接口0/0/0.1和0/0/0.2并配置网关及掩码
<Huawei>sys
[Huawei]int g0/0/0
[Huawei]undo shut
[Huawei]int g0/0/0.1
[Huawei-GigabitEthernet0/0/0.1]dot1q termination vid 10
[Huawei-GigabitEthernet0/0/0.1]ip add 192.168.10.1 24
[Huawei-GigabitEthernet0/0/0.1]int g0/0/0.2
[Huawei-GigabitEthernet0/0/0.2]dot1q termination vid 20
[Huawei-GigabitEthernet0/0/0.2]ip add 192.168.20.1 24
6.子接口开启ARP功能
[Huawei-GigabitEthernet0/0/0.2]arp broadcast enable
[Huawei-GigabitEthernet0/0/0.2]int g0/0/0.1
[Huawei-GigabitEthernet0/0/0.1]arp broadcast enable
7.验证：能使PC1 ping PC2
PC>ping 192.168.20.10
Ping 192.168.20.10: 32 data bytes, Press Ctrl_C to break
