要求LSW4和LSW6使用基本QinQ实现通信,打上vlan 2；LSW3和LSW5使用灵活QinQ实现通信，并且对于vlan30的数据打上vlan2的标签；对于vlan40的数据打上vlan3的标签
命令配置 基本QinQ配置首先在LSW1及LSW2上创建VLAN2和3：在LSW4和LSW6上创建VLAN10和VLAN20
[LSW1]vlan batch 2 3[LSW2]vlan batch 2 3 [LSW4]vlan batch 10 20[LSW6]vlan batch 10 20配置链路类并划分vlan
[LSW1-GigabitEthernet0/0/3]port link-type trunk[LSW1-GigabitEthernet0/0/3]port trunk allow-pass vlan all[LSW2-GigabitEthernet0/0/3]port link-type trunk [LSW2-GigabitEthernet0/0/3]port trunk allow-pass vlan all[LSW4-GigabitEthernet0/0/1]port link-type access [LSW4-GigabitEthernet0/0/2]port link-type access[LSW4-GigabitEthernet0/0/1]port default vlan 10[LSW4-GigabitEthernet0/0/2]port default vlan 20[LSW4-GigabitEthernet0/0/3]port link-type trunk [LSW4-GigabitEthernet0/0/3]port trunk allow-pass vlan all[LSW6-GigabitEthernet0/0/1]port link-type access[LSW6-GigabitEthernet0/0/2]port link-type access[LSW6-GigabitEthernet0/0/1]port default vlan 10[LSW6-GigabitEthernet0/0/2]port default vlan 20[LSW6-GigabitEthernet0/0/3]port link-type trunk[LSW6-GigabitEthernet0/0/3]port trunk allow-pass vlan all配置基本QinQ
[LSW1-GigabitEthernet0/0/2]port link-type dot1q-tunnel [LSW1-GigabitEthernet0/0/2]port default vlan 2[LSW2-GigabitEthernet0/0/2]port link-type dot1q-tunnel [LSW2-GigabitEthernet0/0/2]port default vlan 2验证配置
至此，基本QinQ配置完成
灵活QinQ配置配置链路类型
[LSW3-GigabitEthernet0/0/1]port link-type access [LSW3-GigabitEthernet0/0/1]port default vlan 30[LSW3-GigabitEthernet0/0/2]port link-type access[LSW3-GigabitEthernet0/0/2]port default vlan 40[LSW3-GigabitEthernet0/0/3]port link-type trunk[LSW3-GigabitEthernet0/0/3]port trunk allow-pass vlan all[LSW3-GigabitEthernet0/0/3]port link-type trunk[LSW3-GigabitEthernet0/0/3]port trunk allow-pass vlan all[LSW5-GigabitEthernet0/0/1]port link-type access [LSW5-GigabitEthernet0/0/1]port default vlan 30[LSW5-GigabitEthernet0/0/2]port link-type access [LSW5-GigabitEthernet0/0/2]port default vlan 40[LSW2-GigabitEthernet0/0/3]port link-type trunk[LSW2-GigabitEthernet0/0/3]port trunk allow-pass vlan all配置灵活QinQ

至此，配置完成
