9.6.3 Example for Configuring VLAN-based BPDU Tunnels

Networking Requirements
As shown in
BPDUs of the CE devices are transmitted through the ISP network. Each port of a PE is a
convergence port. Therefore, the PE devices need to distinguish BPDUs sent from different user
networks according to the VLAN tags of the BPDUs. In this case, you can configure VLAN-
based BPDU tunnels to ensure that:

Figure 9-9, 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.
