Spanning Tree Protocol

Spanning Tree Protocol

The Spanning Tree Protocol (STP) is a protocol used in bridged or switched networks to prevent loops, which can cause broadcast storms and other network problems. The protocol creates a spanning tree topology for the network, with a single active path between any two network nodes.

STP operates by selecting a root bridge for the network and then calculating the shortest path to that bridge for each network segment. This path becomes the active path, while all other paths are blocked. If the active path fails, STP recalculates the path to the root bridge and activates a new path.

STP is essential in preventing network loops, which can cause a lot of problems in a network. By creating a single active path between any two network nodes, STP ensures that there are no loops, which can cause broadcast storms and other network issues.
