Spanning-Tree Protocol (STP) is a Layer 2 link management protocol that provides path redundancy while preventing loops in the network. The STP uses a spanning-tree algorithm to select one switch as the root of a spanning tree. STP determines the topology by transmitting Bridge Protocol Data Unit (BPDU) packets between devices. Spanning-tree operation creates a stable network.
