one of the best ever video tutorial on STP...I learned a lot about this topic. Thank you for using diagrams and and Switches to make things way easier to understand for viewers like me.
Wish my English were good enough in order to express to you how good teacher you are (and i'm very strange person when the time comes to rate a teacher). I will only say this: Wish i had a teacher like you in every study of my life. Sorry if my English confused you and thank you very much for helping us.
I watched some Video of your playlist to refocus on specific topics and get prepared for the new CCNA .... and i passed today! Thank you especially for that great video about STP. Now i will always relate GOLF to STP and never forgot the 802.1w Next step is the road to CCNP :) Greets from Germany Micha
Every Time ..Every Time!! I learn at least one thing from your videos. This is so frustrating because others have made this so difficult to understand and you make it so easy. Thank you
I'm studying Cyber in Australia, and we are studying Cisco packet tracer. If it wasn't for Keith Barker I would not have passed the first Semester. And now I'm doing Semester 2, it's Keith Barker to the rescue again. Thank Keith. So informative and easy to watch. I'm grateful to you (and have recommended this channel to all the students and the lecturers as well!)
Thanks for these generous video Keith, it is really fun watching your videos i really enjoy them. keep up the good work. you are the best teacher on networking!
You sir, are an excellent instructor. It was a very well presented lesson of Spanning Tree Protocol, and the first time I ever got a grasp of WTH it does and why it's important.
One of my first time writing a comment, one of my first video's of 1 hour of content which i watched. You're a legend for how you explain all of this, most definitely i am gonna watch your other videos (be)for(e) my CCNA exam!
Thank You! I'm actually working on Network+ but have been watching some of your videos and they are very helpful. Your positive and happy vibe is very engaging and before I knew it the entire hour+ had passed.
Awesome explanation of how STP works. I appreciate the time and effort you dedicate to teach and make the content available for millions of people globally.
Keith, you're the best. Love watching your channel and learn about network technology. Great explanation about how stp works. Please continue producing great learning videos for us.
Hi, may I please ask why Wireshark shows the ARP request's Target MAC Address as 00:00:00:00:00:00 when we're actually broadcasting to FF:F:FF:FF:FF:FF? (Video Time - 7:30)
Great question. In the payload of the ARP request, the device sending the request doesn't yet know the target's MAC address. That is why the target is set (in the payload of the ARP request) to all 0s. The destination in the Layer 2 header is the L2 broadcast of all 1s (Hex all Fs). Hope that helps, and happy studies. :)
Really love that energy! Thanks for making networking sounds fun and cool to learn. With this kind of presentation, definitely will attract people to learn networking :D
I totally agree! Keith you are so enthusiastic and energizing to listen to. I can tell you know your stuff and you have a gift for teaching. Thanks for taking the extra time to explain every little detail and using wireshark to prove theories. Great explanation metafors too. You're the man! Greetings from Sweden/Stockholm
This is fantastic. I am self studying with the Wendell Odom books and your instruction fills in the gaps well with topics that are hard to understand directly from reading these books from Wendell. Thank you again!
You're the best teacher ever In addition to your Information, your spirit and your way are so captivating I'm really really thankful for you and your great efforts
Thank you Keith for this!! Am currently preparing for my CCNA and Wendell Odom's book got too much into detail and lost me completely on this topic. Now i can clearly understand based on your hand drawn illustrations👏👏👏🙌
a very clear explanation about the STP. I understood everything in one go except for the last bit. Which I will have to go over again. Thanks so much Keith. ok...2nd review done : now my knowledge is solid.😀
Many thanks this has really hepled to consolidate this important topic. I first watched Jeremy on CBT then youself, great work always learning from you
Happy to help and thank you for the comments! Feel free to join my Discord sever. Lots of people there helping each other out. Each Saturday at 10am Pacific I hold my "Office Hour" where learners can ask questions about the topics they are studying. Mostly focusing on Cisco CCNA 200-301 topics. Feel free to join us there live if you are available. Here is the link ogit.online/Join_OGIT_on_Discord Thanks again!
Hi Keith...about 9:47 this video hits a snag. Goes from taking about a L2 header to dogs mushing. Definitely lost me there. But I'll keep on. Great Video as always.
Great way to explain Keith. Would have been done with CCIE I'd I had gotten your channel earlier. Stuff here. I'm on to CCNP but brushing up with this before I enter that. I won't stop till I get CCIE.
Great explanation video! I read through the chapter in the cert guide but it was a little confusing. This helped a lot in my understanding! Would recommend also reading the chapter for the nit picky details Cisco likes to quiz on.
Please do a second session for Spanning Tree. Also show how you do a secondary as in the spanning-tree vlan 10 root primary/secondary. Also mention more in the next STP video for MSTP,RSTP,CST and give us more basic information about the various STP variants so its not just towards the new CCNA 200-301 cert. Also mention the cost of fast ethernet and 10Gbit ethernet aswell. I have watched a STP video from Laz last week I belive, I'm watching yours aswell to see who has the best information and what the other person left out. Maybe little too much of layman term explaining,but overall a good video.
@@KeithBarker Mr can you please give me your phone number and your email because I have only one question that I do not know how to solve it can you do it for me
@32:47 - what about sw1 port 3/2, that's red, so trunking. it should send bpdu ???? @40:04 - bpdu are sent to access access port as well ??? @47:11 - doesn't each port on a switch has it' own mac-address ??? & the switch has a base-mac-address ??? and the each vlan has a mac-address ???
Hi Keith - When are you coming back on RUclips - Discord - You have literally transformed my learning study path in Networking👍 The live quiz that you used to do on a Sunday was fantastic please bring it back 😊
Thank you @keithbarker ! I am studying for CCNA and your videos are really helpful! You are a great teacher! I appreciate what you have done years ago and probably you are currently doing and I am following your unaging videos right now. Question: Some of your videos are somehow cut in between, like if there was a copyright claim or something. I am not sure if I am missing out something, you could check if you want: 9:45
Hey Keith, thanks for the wonderful video. A quick question. @43:30, if we assume that everything in this network topology stays the same, except SW3 and SW2 are connected via Fast Ethernet with the cost of 19, SW3 2/3 would still be designated port, we would then put SW2 2/2 interface in a blocking state? Would SW2 3/0 then become Root port, with SW1 0/0 becoming Designated, and SW2 1/3 would become Designated, and SW1 1/2 would become undesignated? Did I guess it correctly? I'm really struggling with this one and I am watching this for the 6th time, but I am eager to get my CCNA and won't give up after a few failed attempts. Thanks a lot, you are an amazing dude!
Thank you for the question @marko514. Don't have the time right now to go back through that video and perform a what-if. You may want to lab this one up, in packet tracer or emulator, and test your predictions.
Keith, thanks for the content. However, some of your videos have breaks in them. This one, for example, at 9:37 you are looking at the layer 2 speaking about protection like layer 3. Then it cuts to dogs and mushers. Is there any way of getting these videos reuploaded or fixed? Thanks again for everything
Thank you tippymc4! These were from a live stream, and I don't have a local copy, so no re-upload of the exact content is possible. I will look to see what I can do going forward to prevent any loss of the video or audio. Thank you for your insight!
Keith when you were talking about "Cost" at around 22 minutes in what specifically does that mean? Cost of bandwidth? Monetary Cost? Your unique remedial style of teaching is very easy to learn from. was wondering if you offer 1 on 1 online or over the phone coaching?
I removed the two connections between the SW1 and SW2 and it worked well!! Why was that two connections necessary? Thank u so much! Your videos really helped me. May God Bless you!
Thank you for the question @FaberLSH. Multiple connections can provide fault tolerance, and if using EtherChannel it can also provide for additional usable bandwidth.
59:59 I assume it should be SW2 3/0 to SW1 2/0? Anyway very sincerely thank you for the video. This is the most comprehensive visualization of STP I have seen thus far. Also, was wondering if you have video on how to identify and troubleshoot spanning tree loop?
Hi Keith. Do you know of an easy way to reconstruct the switch topology without using CDP or LLDP? Assuming of course that the interface descriptions are also not trustworthy. I think the best way would be using STP output. But I imagine this gets very tricky if only one switch (SW1) connects to the root bridge, while all other switches (e.g. SW2, SW3) reach the root via SW1, by being plugged into SW1 directly. Using only the show spanning tree outputs, I don't see how we could check which interfaces of SW1 switches SW2, SW3 connect to. Although, we could look at SW1's ARP table for that information. Even worse: what if there are additional switches (e.g. SW4, SW5) which reach SW1 via SW2, SW3? Could you perhaps do a demonstration on how to map a network like that? I know it's a bit of a fringe topic, but I'm sure it would be interesting to see. Thank you.
one of the best ever video tutorial on STP...I learned a lot about this topic. Thank you for using diagrams and
and Switches to make things way easier to understand for viewers like me.
Glad you enjoyed it!
You have the best pedagogy of anyone in the IT teaching space. Your mnemonics are so memorable.
Thank you seth jones!

Thank you ezautorepair!
Best video on STP, apparently the 13 people who did not like this video, still do not understand STP, and most likely failed their CCNA test.
Thank you Seth Raymond
I'm studying Cyber in Australia, and we are studying Cisco packet tracer. If it wasn't for Keith Barker I would not have passed the first Semester. And now I'm doing Semester 2, it's Keith Barker to the rescue again.
Thank Keith. So informative and easy to watch. I'm grateful to you (and have recommended this channel to all the students and the lecturers as well!)
Took my CCNA the other day after coming to this video to reinforce spanning tree concepts and got a pass. this video came in clutch for me on my exam.
Congratulations @neage7171❗
So great to hear, way to get it done. Best wishes on your continued success.
Thank you keith. Finally I'm able to understand how golf can be played because of STP. Greetings from Algeria.
Keith Barker you are a great teacher my man. Keep it going ? You help clear up spanning tree with this video.
Glad to help

Mr Keith, you are amazing
Thank you a lot
Lots of love

Wow awesome video!👏🏻👏🏻👏🏻i will watch it again and again thank you so much!
Glad you enjoyed it!
You could have short cutted and said that the root port is the switchport connected to the root bridge. But the long explanation is great to know.
Happy new year to you too Keith...we always grateful for such useful information
Thank you Simphiwe! Happy new year to you as well!
Thanks for the stream Keith, loving the new CBT Nuggets content!

Hey Keith, thanks for the wonderful video. A quick question.
@43:30, if we assume that everything in this network topology stays the same, except SW3 and SW2 are connected via Fast Ethernet with the cost of 19, SW3 2/3 would still be designated port, we would then put SW2 2/2 interface in a blocking state?

Thank you for the question @marko514. Don't have the time right now to go back through that video and perform a what-if. You may want to lab this one up, in packet tracer or emulator, and test your predictions.
Thanks for all.
You make everything clear.
You are welcome!
Great lesson, very interactive! thank you Keith!
Thank you XJ JZ!
This guy is amazing.
Question: What does the "ALTN" under the "Role" category - how does that play into Spanning Tree? (Currently at 54:50)
Thank you for the question Priest Apostate. An alternate port is a candidate for a root port, if the current root port fails.
Thank you for such an interesting session on STP.
Btw Nice Tshirt.✌️👌
My pleasure 😊
Thank you for this video. It helped me a lot.
Of Course! Happy To Help!
Thanks, Keith.
Happy to do it, thanks for the feedback Benjamin Wharton.
Keith, thanks for the content. However, some of your videos have breaks in them. This one, for example, at 9:37 you are looking at the layer 2 speaking about protection like layer 3. Then it cuts to dogs and mushers. Is there any way of getting these videos reuploaded or fixed? Thanks again for everything

I vote for router on a stick and Port security! (Since no one else apparently votes for this I want to help ;-) Thanks for the education.
Thank you Bavo Bostoen, great idea. I will add that to my list. Glad you are here.
Keith or anyone , what is the typical default switching method ? I’m getting contradictions in literature. Cut through is default?
Liked it. A very good explanation
Thank you Gideon Kipkoech!
Hi Keith. Do you know of an easy way to reconstruct the switch topology without using CDP or LLDP? Assuming of course that the interface descriptions are also not trustworthy.
I think the best way would be using STP output. But I imagine this gets very tricky if only one switch (SW1) connects to the root bridge, while all other switches (e.g. SW2, SW3) reach the root via SW1, by being plugged into SW1 directly.

Even worse: what if there are additional switches (e.g. SW4, SW5) which reach SW1 via SW2, SW3?
Could you perhaps do a demonstration on how to map a network like that? I know it's a bit of a fringe topic, but I'm sure it would be interesting to see.
Thank you.
Great vid...but what's up with the edit between 9:30 - 9:54 ? Doesn't make any sense...
