9.6.4 Example for Configuring QinQ-based BPDU Tunnels

Networking Requirements
As shown in
BPDUs sent from CE1 and CE2 to the PE devices contain VLAN tag 100. BPDUs sent from
CE3 and CE4 to the PE devices contain VLAN tag 200. You need to configure BPUD tunnels
on the PE devices to ensure that:

To save VLAN IDs on the public network, you need to configure the VLAN stacking function
on the PE devices. That is, configure the PE devices to add outer tag 10 to the BPDUs with
VLAN tags 100 and 200. Then the BPDUs transmitted on the ISP network contain two tags.
In this example, the CE and PE devices play different roles.

Figure 9-10, the CE devices communicate with each other through the PE devices.
All the devices in VLAN 100 participate in calculation of a spanning tree.
All the devices in VLAN 200 participate in calculation of a spanning tree.
The CE devices function as customer bridges. The default destination MAC address of
BPDUs sent from the CE devices is 0180-C200-0000.
The PE devices function as the provider bridges. The default destination MAC address of
BPDUs sent from the PE devices is 0180-C200-0008.
