Thanks all.

Thanks for explaining this.

Thanks for the explanation.

Thanks all.

Because BPDU is sent from switches which operate at Layer 2 i.e. the Data Link Layer.

What is a layer 2 device mentioned in the question?

Bridge Protocol Data Units (BPDUs) is used by bridges in a network to exchange information regarding their status. The Spanning-Tree Protocol uses the BPDU information to elect the root switch and root port for the switched network, as well as the root port and designated port for each switched segment.

It stands for Bridge Protocol Data Unit. BPDUs are data messages that are exchanged across the switches within an extended LAN that uses a spanning tree protocol topology. BPDU packets contain information on ports, addresses, priorities and costs and ensure that the data ends up where it was intended to go. BPDU messages are exchanged across bridges to detect loops in a network topology. The loops are then removed by shutting down selected bridge interfaces and placing redundant switch ports in a backup, or blocked, state.

Please give me define the BPDU.
