One of these protocols is MSTP (Multiple Spanning Tree Protocol), and in this article, we will explore how MikroTik RouterOS implements MSTP to improve network stability and efficiency.

What is MSTP?

MSTP, or Multiple Spanning Tree Protocol in Spanish, is an extension of the well-known STP (Spanning Tree Protocol) protocol. STP was originally developed to prevent loops in Ethernet networks, which could occur when you have multiple paths between devices.

However, STP has some limitations, such as the lack of ability to leverage the full capacity of a backbone network with redundancy.

MSTP solves this problem by allowing a network to be split into multiple spanning tree instances, each of which can have its own independent convergence path.

This means that multiple network paths can be effectively used to transmit data, thereby improving network capacity and redundancy without sacrificing stability.

MSTP implementation in MikroTik RouterOS

MikroTik RouterOS is an advanced router operating system used in a variety of network devices, from routers to switches.

The implementation of MSTP in MikroTik RouterOS is an important feature that allows network administrators to get the most out of their devices and ensure smooth connectivity.

Basic MSTP Configuration

Configuring MSTP in MikroTik RouterOS is relatively simple. Basic steps include:

1. Enable MSTP

First of all, you need to enable MSTP on the MikroTik device. This is done by configuring the protocol on the desired network interface or on the device as a whole.

2. Define MST Regions

An MSTP network is divided into regions, and each region has its own set of spanning trees. In MikroTik RouterOS, an MST region can be configured using specific commands, defining the MST instance and assigning it to the corresponding interfaces.

3. Set Priorities and Costs

To ensure that spanning trees are chosen appropriately, it is important to configure device priorities and interface costs. This is done to influence route selection in case there is redundancy in the network.

4. Check Settings

It is crucial to check your MSTP configuration to ensure it is working as intended. This can be done using specific verification commands in MikroTik RouterOS.

Benefits of MSTP in MikroTik RouterOS

Implementing MSTP in MikroTik RouterOS offers a number of benefits to network administrators:

1. Greater Redundancy

MSTP enables the creation of redundant convergence paths, which improves network availability and fault tolerance. If a route fails, the network can automatically switch to a backup route with no noticeable disruption to users.

2. Better Performance

By leveraging multiple paths in the network, MSTP can increase network capacity and improve performance. This is especially useful on networks with high traffic or bandwidth requirements.

3. Efficient Administration

The ability to divide a network into MST regions makes it easier to manage and diagnose problems. Each MST region can be managed independently, simplifying configuration and maintenance.

4. Avoid Network Loops

MSTP, like its predecessor STP, effectively prevents the formation of loops in the network, which is essential to ensure smooth operation.
