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.
Enable the QinQ (VLAN stacking) function on Layer 2 interfaces of the PE devices.
Configure the PE devices to add outer tag 10 to the BPDUs with VLAN tags 100 and 200.
Inner VLAN tags in the BPDUs that the CE devices send to the PE devices
Outer VLAN tag that the PE devices add to the received BPDUs
IDs of the VLANs that the PE interfaces at the CE side belong to
