9 BPDU Tunnel Configuration
9.6.2 Example for Configuring Port-based BPDU Tunnels (Same
Role)
Networking Requirements
As shown in
BPDUs of the CE devices are transmitted through the ISP network. Each port of a PE device is
connected to only one CE device. Therefore, BPDUs sent from a CE device to a PE device do
not contain VLAN tags. In this case, you can configure port-based BPDU tunnels.
In this example, the CE and PE devices are all configured as customer bridges. The default
destination MAC address of BPDUs is 0180-C200-0000. The PE devices cannot transparently
transmit BPDUs from the CE devices. Therefore, you need to enable the BPDU tunnel function.

Data Preparation
To complete the configuration, you need the following data:
9-32
Figure 9-8, the CE devices communicate with each other through the PE devices.
VLAN100
CE1
GE 1/0/0
GE 1/0/0
GE 1/0/1
GE 1/0/0
CE3
VLAN200
Enable STP on the CE and PE devices.
Add the PE interfaces at the CE side to the specified VLANs.
Disable STP on the PE interfaces at the CE side and enable the BPDU tunnel function on
the PE devices.
Configure the PE interfaces at the PSN side to allow BPDUs from VLAN 100 and VLAN
200 to pass through.
