9 BPDU Tunnel Configuration
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.

Enable STP on the CE and PE devices.
Configure BPDUs sent from a CE device to a PE device to contain the specified VLAN
tag.
Disable STP on the PE interfaces at the CE side and enable the PE devices to transparently
transmit BPDUs.
Configure the PE interfaces at the PSN side to allow BPDUs from VLAN 100 and VLAN
200 to pass through.
Configure the Layer 2 forwarding function on the P device to ensure that BPDUs of the PE
devices can be transmitted on the ISP network.
