How to Change the Root Bridge Election Results on the Cisco CCNP / BCMSN Exam

Are you looking for a way to change the root bridge election results on the Cisco CCNP/BCMSN exam? If so, you have come to the right place! In this blog post, we’ll cover how to make changes to the root bridge election results on the Cisco CCNP/BCMSN exam. We’ll explain the process step-by-step and discuss what factors can affect the election results. After reading this post, you should have a better understanding of how to modify the root bridge election results on the exam and what considerations to take into account when doing so.

The Process of Electing a New Root Bridge
When configuring a Spanning Tree Protocol (STP) in a network, one of the key steps is electing a Root Bridge. The Root Bridge is essentially the device that is the hub of all activity on the STP and it is important that the Root Bridge is correctly selected. This process is typically automatic, however there are times when it can be beneficial to manually configure the election process. In order to do this, the following steps should be taken.

Firstly, each device in the network must be configured with an STP priority. This priority number is used to decide which device will become the Root Bridge Рthe one with the lowest priority number will be elected as the Root Bridge. The default priority number is 32768, however this can be changed to a lower number if desired. Each device should also have a unique bridge ID (BID). The BID is a combination of the device’s MAC address and the priority number assigned to it.

Why Would You Want to Change the Root Bridge Election Results?
Changing the root bridge election results on the Cisco CCNP / BCMSN Exam can be done through a few different methods. The most common of these methods is to adjust the spanning tree priority value, also known as the Bridge ID, on the candidate root bridge. By changing the priority value, you can make one device more attractive to other devices and increase its chances of becoming the root bridge. Additionally, you can also adjust port cost values on non-root bridges to make them less attractive than the chosen root bridge. When the topology of the network changes, it is important to reassess the Bridge IDs and port costs to ensure that the correct device becomes the root bridge.
