QinQ Configuration Example
Network requirements
z
Provider A and Provider B are service provider network access devices.
z
Customer A, Customer B, Customer C, and Customer D are customer network access devices.
z
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.
z
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:
z
VLAN 10 of Customer A and Customer B can intercommunicate across VLAN 1000 on the public
network.
z
VLAN 20 of Customer A and Customer C can intercommunicate across VLAN 2000 on the public
network.
z
Frames of the VLANs other than VLAN 20 of Customer A can be forwarded to Customer D across
VLAN 3000 on the public network.
