QinQ configuration examples
Example: Configuring basic QinQ
Network configuration
As shown in Figure 3:
• 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 in VLANs 100 and 200 for Company A and
Company B, 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.
