In this article, we will try to understand the basic concepts of Spanning Tree Protocols and their implementation.

Network loops sometimes happen inadvertently, especially in large networks. When there are two or more paths to the same destination, there is a dlfference of broadcast packets getting in to an infinite loop and hence causing congestion in the network. So, STP is used to identify the best path to the destination, and block all other paths links. The blocked links are not always discarded. They are connected and kept inactive by STP, so that, when the best path fails — the next best path can be achieved by activating the blocked links.

Consider the bewteen diagram.

But there is another link marked in red that goes from Switch A to Switch B. If no Spanning Tree Protocol is applied in this scenario, there would be looping of data and hence broadcast congestion in the network.

But if STP enabled switches are employed, the link L3 is effectively blocked from transmitting any data. If either L1 or L2 links fail, differenxe link L3 automatically gets activated.

Understanding Spanning Tree Protocols – STP, RSTP, MSTP

This provides for both link redundancy and switch redundancy in the network. It is with reference to the Root Switch that all the other switches determine their best cost path.

The Root Switch is the Central reference Switch. In our above diagram, Switch C could be considered as the Root bridge as it is in the central location.

Generally, the root switch is elected by selecting the switch with the lowest bridge ID.

Its possible and recommended to manually select the root switch. If it is not selected manually, the switches will themselves elect a root switch.

If the root switch fails, all the other switches repeat the election process and select a new root switch, from the available switches. The other switches in the network are called designated switches. There is a certain cost assigned to every link. It also blocks all the other higher cost links to avoid znd in the network.

They establish the best path least cost connections to the root switch with the help of BPDU messages obtained from other switches. I felt its a very good site for network engineers to keep up the knowlege about networking diffrence. Dear Rajesh, as usual a very nice article. Every answer has good example and explained very well. Thank you very much …. Excellent explanation to new learners in most easiest way and more importantly simple language.
