Selective QinQ Configuration Example (QoS Policy-Based Configuration)

Network requirements
As shown in Figure
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 10 and VLAN 20 of Customer A can be forwarded to
Customer D across VLAN 3000 on the public network.
