BPDU protection prevents unauthorized switches from connecting to and participating in your spanning tree topology.

By default, BPDU protection prevents the root bridge from communicating with other STP members unless it receives a superior BPDU first.

BPDU protection requires that STP or RSTP is configured on the switch.
