QinQ configuration example
Network requirements
As shown in Figure 53 :
•
The service provider assigns VLAN 100 to Company A's VLANs 10 through 70.
• The service provider assigns VLAN 200 to Company B's VLANs 30 through 90.
•
The devices between PE 1 and PE 2 in the service provider network use a TPID value of 0x8200.
Configure QinQ on PE 1 and PE 2 to transmit traffic of Company A and Company B in VLANs 100 and
200, respectively.
For the QinQ frames to be identified correctly, set the SVLAN TPID to 0x8200 on the service provider-side
ports of PE 1 and PE 2.
