Configure the devices between PE 1 and PE 2:
# Set the MTU to a minimum of 1504 bytes for each port on the path of QinQ frames. (Details
not shown.)
# Configure all ports on the forwarding path to allow frames from VLANs 100 and 200 to pass
through without removing the VLAN tag. (Details not shown.)

VLAN transparent transmission configuration example

Network requirements
As shown in
•
The service provider assigns VLAN 100 to a company's VLANs 10 through 50.
•
VLAN 3000 is the dedicated VLAN of the company on the service provider network.
Configure QinQ on PE 1 and PE 2 to provide Layer 2 connectivity for CVLANs 10 through 50 over the
service provider network.
Configure VLAN transparent transmission for VLAN 3000 on PE 1 and PE 2 to enable the hosts in
VLAN 3000 to communicate without using an SVLAN.
