Master Spanning Tree (STP) Topologies in 3 Steps

Currently studying for CCNA been using mainly Jeremys IT Lab, but STP got me stumped for a few days. Been going through all other resources like OCG & Neil Anderson & various other YT resources- they just weren't clicking. I have to say your explanation made it made it much clearer for me. SO glad I stumbled upon your video.. Thank you!!!

Thanks, helped clarify stp

Beat explanation out there !! Thanks!!

For rule 3 isn't it the lowest port ID on the destination bridge and not the local bridge?

One of the best STP videos I've seen ever

This was extremely valuable. I'm trying to speedrun getting a CCNA certification starting with very little practical experience and I could not figure out "designated ports" from the book or the lecture content I was provided. The way you covered it is extremely clear and concise. This channel will be my first resource if I get stumped again and I've put a link to this video in my notes to re-watch when I'm reviewing for the exam. Thank you.

Stumbled on this while killing time, you got me through my CCNA many years ago with CBT Nuggets. Such an infectious personality, cheers Jeremy hope you are doing well.

Been struggling on this topic but you help to clearify it all! Tahk you!

Maybe I’m overthinking it. Lol, but what if you have that redundant pair connection between two switches and they cross ports form 1-2.
How would it calculate that?

Is cbt nuggets dining ? 😭

Do you also teach on Khan Academy? Your voice is extremely familiar but I can't place where I know it from.

that was pretty legit. I think its the RP and DP selection that bores people and they lose focus and end up in lala land hating stp or not understanding it.

SO good at drawing... and WRITING!

I would say STP is not about stopping loops. It's about being able to make your network redundant. It also does stop loops. But that happens also outside your topology. Inside your topology you are just using STP to make your links failover when another link fails. If STP is setup correctly, it will NEVER stop 'loops' in your topology. STP can be used for security outside your topology, to stop people from being able to connect switches in circle, outside your topology, and broadcast storm into your network, it will stop that by shooting BPDU out of your edge ports. But it will NEVER and was NEVER designed to just stop 'loops'. Its about REDUNDANCY.

thank you

Dude, you are the BEST! I'm super non-technical, but I'm studying for Network+. I just started learning about STP and I thought my eyes were going to melt. I've looked at countless videos and read countless articles on it and almost decided that maybe I could afford to miss any STP-related questions if I did really good on the rest of the test. I decided to give it one last shot and stumbled across this video. It's like the clouds parted and a brilliant celestial light shone down upon me and bathed me in the resplendent glory of knowledge! When I write my memoirs and reach this milestone I'm giving you a footnote. THANK YOU!

Not the point of this video, but what is the point of the distribution layer in this diagram? Seems like connecting Access directly to Core here would be simpler and lose no value.

Going to the STP question, this all changes if your core layer is running VSS correct?

amazing explanation , thank you so much

GREAT explanation, thanks 👍

I especially love the waaaaaaaaaa, khrr- part of explaining why the need for STP. Anyway, thanks for a great video on topic!

Jeremy is great!

Great video, thank you very much :)

Thanks, your awesome

wondering about the three people how clicked dislike

I first watched your CBT Nuggets back in 2009. Those nuggets changed my life. I now make a ton of money because how you clearly explained switching and routing in a way that made me want to be a Network Engineer, but most importantly it made me excited to learn more and more and more about networks. I learned so much advanced networking over the years, every so often I have to go back to the fundamentals such as Spanning Tree to ensure I never lose how it works. Great 20 minute video!!!

thank you sir

How did you find the blocked ports...??

You and Keith are godsent. Thank you for the motivation and knowledge. You change many more lives then you think.

Do BPDUs only flow through one port in a link aggregation group?

There's a mistake in one of the rules.

Thank you and very informative always.. take care bless you

Thank you. I have a good understanding of SPT now because of you. I appreciate the help. Liked and subscribed. Good day to you Sir.

Thank you so much!!!

amazing way to present this ! great

Watching this video to the end on a Wednesday isn’t a good idea, why isn’t it Friday 🥲

Great stuff. This cleared up so many questions! Thank you

Hello Jeremy
I have question on which layer BGP works..
Could you please make video on it..
I will be thankful.. expecting your acknowledgement

That little zombie analogy tho.. so hilarious

You're the best

we owe you money for this.

Hi Guys,
Let me ask a question, would spanning-tree still block/stop the loop if another pair of type of switch has spanning-tree disabled. The loop is on their end, say a cross-connect between the two switches ?

wow thanks man, helped a lot with my preparing for my exam!

I love this stuff. Spanning Tree is something I've always been good with. Like Jeremy says, just remember those rules and you will understand how it operates. Practice. Practice. Practice.

Amazing job

Cool, cool-cool-cool
