Configuration Roadmap
The configuration roadmap is as follows:
You can configure the basic QinQ function on a CE connected to a PE and implement
communication between two branches of enterprise A through VLAN 20 provided by the carrier.
1. Create a bridge group and add a sub-interface to the bridge group.
2. Configure VLANs allowed by the sub-interface.
3. Configure basic QinQ on the CE interface connected to the PE so that the CE can add the
S-VLAN tag to user packets.
4. Add interfaces of the PE and P to VLAN 20 so that packets from VLAN 20 are allowed to
pass through.
Procedure
Step 1 Create a bridge group and add a sub-interface to the bridge group.
# Create a bridge group and add a sub-interface to the bridge group on CE1. The configuration
of CE2 is similar to that of CE1.
