WebDec 24, 2024 · The Spanning Tree Protocol STP is layer 2 protocol of OSI reference model. STP automatically shut down the redundant links which creates the loops. The redundant link creates a loop between switches. STP monitors all links of the network. Spanning Tree Protocol STP finds the redundant link by the Spanning Tree Algorithm. The Spanning Tree Protocol (STP) is a network protocol that builds a loop-free logical topology for Ethernet networks. The basic function of STP is to prevent bridge loops and the broadcast radiation that results from them. Spanning tree also allows a network design to include backup links providing fault tolerance if an active link fails. As the name suggests, STP creates a spanning tree that characterizes the relationship of nodes …

WebNov 30, 2024 · As a result, Ethernet switches have incorporated a switch-to-switch protocol to construct a subset of the switch-connections graph that has no loops and yet allows reachability of every host, known in graph theory as a spanning tree.
