Spanning Tree Protocol (IEEE 802 1D)

[@haiquannguyen2583]

You know, I spend whole semester to learn STP from my teacher, but just 8 mins to learn this from you, Sunny. Thanks so much

[@sunnyclassroom24]

You are welcome!

[@goodnandnotgoodisgood551]

Now everytime I have something not sure from Cisco Exam or from my work issue, I firstly check Sunny's channel then check RFC, Wiki, book, etc.

[@billylesnussa5087]

Same here, Thanks Sunny

[@lawrencebolt3540]

Thank you. I'm embarrassed how difficult other trainers make this and how simple you made this. Thank you

[@keithchilton5642]

What is nice about learning from Sunny is the fact that he's not unclear about anything that he's presenting. And he knows how to keep that clarity in his explanations. One can only assume, he has deep knowledge of these subjects. Enough so, that he can explain it to even novices. I've always had a mindset of "if you can't explain it to a 4th grader, you don't know it well enough". I think he exemplifies this, so I of course love benefitting from videos like this. Great way to learn!

[@jayrosa2853]

Sunny, I think I speak for many when I say thanks for your easy to understand explanations in all your videos. Much appreciated.

[@sunnyclassroom24]

I appreciate that!

[@ChadFromSpace]

The entire internet, with infinite time, cannot do what you can do, as cleanly or efficiently, in 7 minutes. Thank you.

[@Metalninja89]

Thank you Sunny! This video was extremely helpful. I've been following Jeremy's IT Lab's CCNA course and once I got to STP I felt stuck like I wasn't fully understanding something and after watching your video it now makes a lot more sense. You are by far one of my favorite teachers on KZbin!

[@dagiz0232]

Have u finished the playlist from Jeremy’s course now?

[@Metalninja89]

@@dagiz0232 I actually paused Jeremy's course for the time being because I realized I wanted to get my CCST certification first so I've taken a few courses for that since then. My test is this Saturday though so hopefully I pass and I'll be right back into Jeremy's course to hopefully get my CCNA.

[@dagiz0232]

@@Metalninja89 Do you have any tips(sources) on learning Subnetting?....I didn't fully understand it from Jeremy?.............................Oh and Good Luck on your test on Saturday!!!

[@Metalninja89]

@@dagiz0232 Thanks for the wish of luck. To try and help you out with Subnetting, I personally think Sunny has an amazing video on Subnetting. To give you a little more to work with though I also really like Professor Messer on KZbin as well if you haven't come across him yet. Lastly, I took a course on Udemy from Kevin Wallace who overall was pretty good but I did think that he explained Subnetting well. What I found on KZbin is a 2 hour deep dive into Subnetting which may be helpful for you. Keep at it, you'll get it eventually. Sometimes you just need to hear it explained differently or sometimes you just need to come at it at a different point in time.

Just spent weeks trying to understand and just explained everything clearly under 10 mins. Thank you

[@vladislavkaras491]

It is a great idea to first show theoretically how everything works, and then show deep in the details, how every single step happens. Thanks for the video!

[@vfacuu]

x1.5 speed, this was the most useful video explanation of STP. thank you

Whenever I have difficulty I come to sunny, he is absolutely clear. Thank you

[@garnetthegeman6838]

I have been studying STP for two months and never really clearly understood it. But Sunny made it clear in less than 5 minutes. Truly awesome. Thank you, Sunny!

[@Progmium]

I have seen many videos on this. Yours is the clearest to understand by far! Thanks!

[@mpersonman33]

Great video. The first video I've seen so far that can actually explain this clearly.

[@DaniloSouzaMoraes]

I agree and ive seen lots of videos. The fact that he chose to teach with 4 switches instead of 3 helped answered many of the questions i had.

[@africanxpress9185]

Thanks. With the animation and graphic in your videos tutorials you become one of the few making CCNA understandable and accessible to us newcomer into the networking field for the first time.

[@hosseinbeiranvand7169]

[@ntgc-tv]

Thank you for your great works... Which root will be taken if the cost DBA = DCA?

[@cconer]

As Wikipedia the STP page: The sequence of events to determine the best received BPDU (which is the best path to the root) is: - Lowest root bridge ID - Determines the root bridge - Lowest cost to the root bridge - Favors the upstream switch with the least cost to root - Lowest sender bridge ID - Serves as a tie breaker if multiple upstream switches have equal cost to root - Lowest sender port ID - Serves as a tie breaker if a switch has multiple (non-Etherchannel) links to a single upstream switch, where: + Bridge ID = priority (4 bits) + locally assigned system ID extension (12 bits) + ID [MAC address] (48 bits); the default bridge priority is 32768, and + Port ID = priority (4 bits) + ID (Interface number) (12 bits); the default port priority is 128. I think the "Lowest sender port ID" cant be the same cost.
