Spanning Tree Protocol
The Spanning Tree Protocol (STP) is a part of the IEEE 802.1D standard that provides for redundancy in a bridged LAN by allowing multiple links between points in the LAN.
Without the use of STP, multiple links in a bridged network will result in bridging loops, which allow excess broadcast traffic that can bring down an entire network.
Overview
The Spanning Tree Protocol reduces a network with multiple, redundant connections to one in which all points are connected (the protocol spans the network), but in which there is only one path between any two points (the paths are branched, as in a tree).
For example, in a large network with multiple paths, the same message will be broadcast over the network through multiple paths, resulting in a great amount of extra network traffic, and possibly, network downtime. This “closed path” or “bridged loop” among the networks can also start an unending
IImportant: To explain STP more effectively, the IntraC- ore 8000 is described as a bridge for this section of the manual.
