Spanning Tree Protocol (STP) Deep Dive

Sir Kevin Wallace you are explaining everything in a crystal clear manner. I am getting guidance in almost everything related to networking by watching your videos. You are computer network genius. Thank you so much ❤

Thanks KWTraining for this awesome clarification on STP. As it is inevitable in our networks today, understanding how to work with it is essential and you really make it clear here...

Thanks this was an amazing video!

I am new in Cyber technology and I came across a problem related to STP. This is the best presentation I found, you explanation are very clear, your examples are different (tricky) ... and I am just half throu the presentation. I cant wait to see the lab!!!thanks for posting. Great work

amazing

It's a bane of a network engineer's life having to confront Cisco's proprietary features in a heterogenous network environment. It also amazes me that after decades of these features, there's not been more alignment between IETF standards and vendor-specific issues. While the likes of program languages strive for open standards, hardware vendors seem to work against each other. There shouldn't be a need to have to create workarounds for the likes of Cisco, Brocade and Arruba systems to work on LANs.

"Can anybody remember the Cisco 1900 switch?.."
L0L!
Here I am - part of a crew running a small-medium sized ISP network... and some of our Broadband Wireless switches are Cisco 1900XL switches! We have 10 of 'em in active service!😀
They were bought way back in 2003 and served in various segments and capacities over the years. Of all the switches- including the old 2960s, 3650s etc- we've not had a SINGLE 1900XL fail EVER in our network- even when they were running in the core some 15 years ago. Kevin calls his 6509 "The box that rocks", I call these the "the pocket rockets!" 😀
Those things will never die! (unless you need more than 100Mbps of course..)

Time to recert, I'm still coming back to you. My first Cisco cert was in 2018!!!

These deep dive videos are amazing content. Thank you for sharing!!

That's interesting to hear your story about Disney because I was on the team that installed those Cisco 2600 Catalyst switches on a project called the Walt Disney high-speed internet access project I believe it was 2001!

You have explained the concepts that appeared complex, so well and made them easily understandable. Once again, thank you Kevin.

Rank 1 content, thank you!

I loved the report regarding Broadcast Storm… kkkkk.. great experience and cleverness

I am just 20 mins into this lecture, i have been awake over night till now for about 36 hours or more, and i am really enjoying learning and listening very much I am not sleepy anymore...feels like i found someone to follow on my networks learning journey, i am so happy really

Excellent lecture as always. Requesting you for VPN deepdive and packet analysis right way.

Kevin you are a real asset to the networking community. After I pass Encor I'll definitely be buying your ENARSI video course.

i appreciate a lot this video . i was really struggling to learn spanning tree. the way how you explain its very clear and easy . Thanks a lot

this is amazing, thanks Kevin

I appreciate this video. I struggled to retain a lot of the fundamental concepts of the STP, including the differences and similarities between the different versions. For some reason between the text book and a couple video courses I watch, I couldn't get it down solidly. I like that you really spent the time to explain everything concisely and clearly with examples. I feel confident that I understand it now and I feel ready to move onto the next part of my CCNA learning!

Kevin is that dummy phone behind you or its live..

It's always switches all connected to each other. Never explained how it works in a more cascaded topology with several hops/switches in between. Let's say we have SW1-4. Connected like SW1 -> SW2 -> SW3 -> SW4. SW1 is the core switch and root bridge and SW4 an access switch. Does SW4 (with NO direct connection to SW1) see SW3 as his root bridge or is it also SW1 in the STP table? The SW4 -> SW3 connection will be the Root port, but will it also show the bridge ID of SW1 as the root or SW3?

Hi kevin is this the same as STP topics in a CCNP ?

1

11 because it has 10 at the end of equation

Why FAS0/3 of SW3 is designated port ? SW3 is not the Root Bridge

This dive has been wonderful. Thank you for your contribution.

Thank you Kevin -- another great session -- I'm currently running through all your 'deep-dive' tutorials for my CCNA 200-301, very easy to follow and can't recommend enough to other students. Packet Tracer is capable of covering most of the content should anyone require hands-on. Thanks again 🙏

These deep dives are gold!!

Thanks much!

Thanks for the class professor.

So many very real-life valuable details derived from many lessons-learned I guess, thank you.

Which Is The Objective Of The Ports Designated In Stp If The Root Port Sends Bddu Also This Has Me Very Confunsed I Look And Search On Internet And I Do Not Find That Doubt??????????

Cheers Mate.

Thanks for the passion, and thess precious info 💙

Excellent- Explanation of the over all process of Spanning Tree

why did you multiply by 7 for the pvst + rapid

how do you know what to multiply by regarding the primary and secondary when you changing the switches roots

SW1

It's really amazing work I love snd easy understand

Very nice. I love your resume and your history lessons. I worked at DEC on PDP 11 and VAX 750/7800 systems in 80's and did not know that STP originated from one of my co-workers 😆.

Awesome thank you

Amazing instructor. 🌹
