Configuring devices in the service provider network
All ports on the path between PE 1 and PE 2 must allow frames from VLAN 100 and VLAN 200 to pass
through without removing the VLAN tag. (Details not shown.)

Network requirements
As shown in Figure 39 , the two branches of a company, Site 1 and Site 2, are connected through the
service provider network and use VLANs 10 through 50 and VLAN 3000. VLAN 3000 is the dedicated
VLAN of the company. PE 1 and PE 2 are edge devices on the service provider network.
Configure QinQ and VLAN transparent transmission to enable the two branches of the company in
VLANs 10 through 50 to communicate through VLAN 100 allocated by the service provider, and enable
the hosts in VLAN 3000 to communicate without using a SVLAN.

Configuration procedure
This example assumes that the CVLANs have been configured correctly on the CEs.
Configuring PE 1
1. Configure Ten-GigabitEthernet 1/0/1 (the customer-side port):
# Configure Ten-GigabitEthernet 1/0/1 as a trunk port, and assign it to VLANs 10 through 50,
VLAN 100, and VLAN 3000.

# Set the PVID to 100 on the port.
