QinQ 实验

实验拓扑图

实验要求

LSW4和LSW6使用 基本QinQ 实现通信,打上 vlan 100 ；
LSW3和LSW5使用 灵活QinQ 实现通信，并且对于 vlan30 的数据打上 vlan100 的标签；
对于 vlan40 的数据打上 vlan200 的标签

基本QinQ

配置思路

• 先创建需要的vlan，再把各个端口加入所属的 vlan 中
• 其中交换机相连的口配trunk，其余配access
• 把 LSW 1 的2口 和 LSW 2 的 3口 配置QinQ

配置过程

SW4:

vlan batch 10 20   
#

interface GigabitEthernet0/0/2        
 port link-type trunk                 
 port trunk allow-pass vlan 2 to 4094   
#                                     
interface GigabitEthernet0/0/3        
 port link-type access

interface GigabitEthernet0/0/3          
 port link-type trunk                   
 port trunk allow-pass vlan 2 to 4094

 port link-type dot1q-tunnel            
 port default vlan 100                  

SW6:

 port default vlan 20                   
#                                       
interface GigabitEthernet0/0/3          
 port link-type access                  
 port default vlan 10

灵活QinQ

配置思路

• 将终端设备接口改为access，交换机之间用trunk。
• sw1 和 sw2 的g0/0/1和g0/0/2口做转换，添加映射关系
