When STP works stably on the customer network, if Customer A acts as the root bridge, the ports of
Customer C and Customer D connected with Provider C can receive BPDUs from Customer A. Since
BPDU isolation is enabled on Customer B, the port that connects Customer B to Provider B cannot
receive BPDUs from Customer A.
