The requirements are as follows:
l VLANs are assigned independently in enterprise A, and are independent of carrier VLANs
or VLANs of other enterprises.
l Traffic between two branches of enterprise A is transparently transmitted through the public
network, devices transmitting the same service in different branches of enterprise A are
allowed to communicate, and devices transmitting different services are isolated.
l High-priority voice services are transmitted first.

Configuration Roadmap
The configuration roadmap is as follows:
You can configure selective QinQ on the CE user-side interface and implement communication
between two branches of enterprise A through VLAN 20 and VLAN 21 provided by the carrier.
1. Create a bridge group and add sub-interfaces to the bridge group.
2. Configure VLANs allowed by the user-side sub-interfaces of the CE, configure the CE
user-side interface to add different outer VLAN tags to packets with different user VLAN
IDs, and re-mark voice services with high priority.
3. Add the CE interface connected to the PE, PE interface, and P interface to VLAN 20 and
VLAN 21 so that packets from VLAN 20 and VLAN 21 are allowed to pass through.
Procedure
Step 1 Create a bridge group and add sub-interfaces to the bridge group.
