Introduction - Switching Redundancy problems0:41
This lecture is an introduction of what I am going to explain in the upcoming video regarding problems with Switching Redundancy.
Explaining Problems on Redundant switching without using STP11:02
In this lecture, I am going to explain what are the problems that you will have in redundant switching if you don't apply the STP protocols. The main problems are:
Broadcast Storm
Multiple frame copies received
MAC address instability

Introduction to Spanning-Tree Protocol0:57
Explanation of how Spanning-Tree works15:16
In this lecture, I will explain how Spanning-Tree works such as:
How the switches elect the root bridge
What is the bridge ID
What is the BPDU
What are the different port names in Spanning Tree: Designated, Root Port, Alternate, etc...
What is the root path cost
Explanation of Interfaces States in STP Protocol8:32
In this lecture, I will explain to you what are the different states that an interface on the MikroTik switch participating in the STP algorithm will have.

You will have a deep understanding on the follow states:
Blocking
Listening
Learning
Forwarding
Disabled

Introduction to the STP LAB1:34
In this lab, set up three switches in a redundant topology, connect two computers, configure STP, and observe designated versus alternate ports and convergence when a link is removed.
Configure your RouterBoards to be Switches and enable STP protocol14:12
In this lecture, I am going to show you how you can make your Routerboards as switches by using Bridge interfaces and Hardware Offload, and how to add the physical interfaces to the Bridge.
Also I will show you how you can enable STP on your switches.
Checking if STP is working properly on the switches12:50
In the 2nd part of the LAB, I am going to show you on the graph which of the switches should be the root bridge and what are the port roles for each of the switch, then we compare that to the real switches and check if they are identical.

Then I am going to show you how long does it take when you remove a cable for the STP to re-converge the network again.
Manipulate the STP configuration24:59
Configuring Port Priority on STP11:29
When you have 2 switches connected via a redundant way to each other via 2 ports, one of the switch will be the root bridge and the other the non-root bridge. The non-root bridge will have one of its port to be the Root Port and the 2nd port the Alternate. In this LAB, I will show you how the non-root bridge select which of its 2 ports become the Alternate and based on what he takes the decision, then I will show you how you can change this selection by using the port priority feature.
Topology Change Notification (TCN) in Spanning-Tree17:29
In this lecture, I am going to explain about the TCN and how it affects the spanning-tree protocol. With TCN, our layer 2 network works in an efficient way.

Introduction to Rapid Spanning-Tree Protocol1:27
Difference between STP and RSTP9:11
In this lecture, I am going to show you what is the difference between the STP and the RSTP such as port states name, BPDU sent mechanism, speed of STP, Backup port on RSTP and so on.
Understand the Negotiation Mechanism in RSTP6:30
We have seen that in STP, for the port to go on Forwarding it has to pass via listening, learning until it goes into forwarding state. This takes up to 50 seconds in case the port is in a blocking state.
In RSTP there is no timers as in STP but instead there is a negotiation (synchronization) mechanism which makes the RSTP make the switch port goes much faster into forwarding state.

In this lecture, I will explain to you how this mechanism works in the RSTP,
Configuring RSTP on MikroTik Switches15:24
In this lecture, I will configure RSTP on the 3 switches and will check how fast it can re-converge the network when one link goes down. Also I will explain what are the functions of Edge ports and Point-to-Point ports and how we can benefit from them.

Introduction - Multiple Spanning-Tree Protocol1:28
What is Multiple Spanning-Tree Protocol?9:50
In this lecture, I am going to explain to you what is the function of the Multiple Spanning-Tree Protocol and how to use it. You will understand what is needed to be made to configure MSTP on the MikroTik Switches.
Configuring Multiple Spanning-Tree on MikroTik Switches15:43
In this lecture, I am going to do a LAB showing you to configure MSTP on MikroTik Switches.
This will include:
Setting the protocol mode to MSTP
Creating Region name and Region revision number of the 3 switches
Map the VLAN's to the right MSTI identifier
Change the root bridge election for the 2 different identifiers
By the end of this LAB, I am going to justify if the whole work has been done correctly.

Requirements

Have a basic networking skills
Understand the TCP/IP protocol
Have some hands-on on MikroTik products and Winbox tool

Description

This is the first course in the market discussing about switching in MikroTik. Since RouterOS version 6.41 and above, MikroTik has very reliable Switching features that you can profit from: One of the feature is the Spanning-Tree Protocol.

Spanning-Tree Protocol (STP) help your redundant switching networks to avoid having loops and to wok efficiently. Without STP your network would end up not working. In this course, I am going to discuss in details how STP works and what are its features, also I am going to discuss about the RSTP and the MSTP (MSTP is only available on RouterOS version 6.41+).

To be able to do the LABS in this course, you need 3 MikroTik routerboards having a switch chip, or you can use MikroTik CRS models. You also need 2 end devices such as PC's.

I look forward to see you in my course.

Who this course is for:

Engineers who would like to upgrade their knowledge in MikroTik Switching
Engineers who want to apply Spanning-Tree Protocol in their network
Students who want to learn how MikroTik Switching Spanning-Tree protocol works
