The configuration of outer VLAN tag priority is achieved through QoS policies. For more information
about QoS policies, see QoS Configuration Approaches in the ACL and QoS Configuration Guide.
QinQ Configuration Example
Network requirements
Provider A and Provider B are service provider network access devices.
Customer A, Customer B, Customer C, and Customer D are customer network access devices.
Provider A and Provider B are interconnected through a trunk port, which permits the frames of
VLAN 1000, VLAN 2000, and VLAN 3000 to pass through.
Third-party devices are deployed between Provider A and Provider B, with a TPID value of
0x8200.
The expected result of the configuration is as follows:
VLAN 10 of Customer A and Customer B can intercommunicate across VLAN 1000 on the public
network.
VLAN 20 of Customer A and Customer C can intercommunicate across VLAN 2000 on the public
network.
Frames of the VLANs other than VLAN 20 of Customer A can be forwarded to Customer D across
VLAN 3000 on the public network.
