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!
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 RUclips!
@@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.
@@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!!!
@@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 RUclips 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 RUclips 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.
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!
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!
I have watched videos on this topic while studying for the Network+ certification on both Udemy and LinkedIn Learning and couldn't understand a thing. Thank you so much for your clear, straight to the point explanation!
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.
Bonjour Sunny : An outloud "hello" from France. Many, many thanks to you : Your numerous video courses are trully awsome : Really synthetic, remarkably intelligent and totally clear. You make computer technology even more attractive, simple and funny to learn. Best regards, Olivier
Sir Selection of the Designated & Blocked Port is based on Lowest Cost then Lowest Bridge ID then Lowest Port number. You said based on Lowest Bridge ID
Thank you so much Sunny, only now I have understood STP especially where the term come from when you introduce the Complete Graph and Spanning Tree theory. You always give us a very clear picture. Thank you.
OHHHHHH Shhhhhhhhttt!!!! Wow thank you so much!!! I was lost on this topic. You've explained it so clear and easy for a newcomer like myself! Thank You so much!
One of my favourite educational RUclips channels. I am an undergrad networking student and your videos has helped me pass in so many courses. Thank you so much and keep up the good work!!
Sunny, Thank you. You obviously know Networking very well, your communication and simplicity in explanation, while maintaining technical accuracy is superior to most training I have seen. Thank you or taking the time to clarify this so well for me. '
Sunny, Really I am very happy with your tutorial because I am searching video like your video from later 3 year & now my searching stop on your video. Fantastic sunny weldon. Keep it up. I ma from india
Hi Sunny, You are great, I was strugling to learn STP and now after watching this I am able to imagine all points and also got the importance of blocking ort in STP. Thanks for such great hard work. Keep going on
Thank you so much for providing such excellent and clear explanations of networking topics and definitions. Your videos are helping me so much to understand the concepts in my classes. Thank you!
Thanks Sunny! One suggestion to make this a little clearer. Maybe have PC-1 connected to Switch A so it is clear that the ultimate destination of the frame is PC-1. THANKS AGAIN!
Great video as always but I do not agree in the designated port selection. In my understanding the designated ports are selected as the port for a collision domain which its path cost to root is the lowest. So, first you determine all the root ports, and then 1 designated port per collision domain (in the example all the collision domain are just of two ports because there are no HUBs). Finally, the rest of the ports are blocked.
thank you sooo much sir, this is the best explanation ever, but i have a question, in 6:28 , what if both DCA and DBA costed 4, which one should e choose then?
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.
i understand the selection process but i dont understand why switch C has a designated port on a link that is inactive anyway. Why do these inactive links still require a designated port?
These inactive links are temporary. We consider them as back up. In case active links are down, they will be up and running. That is why they still require designated port.
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
You are welcome!
Same here
@Kyree Terrance 😂😂
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.
Same here, Thanks Sunny

Sunny, I think I speak for many when I say thanks for your easy to understand explanations in all your videos. Much appreciated.
I appreciate that!
The entire internet, with infinite time, cannot do what you can do, as cleanly or efficiently, in 7 minutes. Thank you.
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!
Best network teacher on youtube!
Just spent weeks trying to understand and just explained everything clearly under 10 mins. Thank you

I LOVE THE CHINGLISH LANGUAGE. I UNDERSTAND THIS WAY MORE THAN MY INSTRUCTOR WHO SPEAKS FLUENT 100% "ENGLISH". THANK YOU SONNY
x1.5 speed, this was the most useful video explanation of STP.

Sunny, you are a natural teacher. Thank you
Great video. The first video I've seen so far that can actually explain this clearly.
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.
Genius!! such an heavy concept, you manage to break it down in simple terms...Thanks Sunny!
Best STP explanation in whole RUclips mate, thank you :)
Nice video its the 3rd one ive seen about the topic and it filled lots of gaps , very much appreciated

Very well and simple explained! Exactly what I was looking for.

I just found your video,it's very useful for me. Thank you teacher Sunny.
OUTSTANDING!!! Many thanks from Delaware! Love you man!! Lol
Glad you enjoyed it
Really wonderful explanation and purpose of it .
Thank you ! You made it so simple
At 6:42 , when you say a non-root switch, do you mean a non-rootBRIDGE switch? THANKS! This is sooooooooooooo helpful! You are a lifesaver!
Thank you once again Sunny!
Thanks man. I learned alot from your videos😘
Easy exlained. Thanks so much!!
You're welcome!
you are like my private tutor in grade 7!!! thanks
very helpful at understanding STP. thank you!
You are welcome!
Thank you for this great work. Which software you used for drawing and animation?
2:45 -> C is a bridge between A and B... this one is correct then
1:48 -> B is a bridge between A and C ???
Sunny is the best❤
Can you write an order in wich we need to watch playlists?
excellent explaining! thanks!
Thank you sir. easy to understand.
Excellent, thank you
You are welcome!
sunny sir thank you soo much you are the best!

I spend hours learning STP I learning from you in 8. Same with other concepts.
thank you sooo much sir, this is the best explanation ever, but i have a question, in 6:28 , what if both DCA and DBA costed 4, which one should e choose then?
BID will be considered. If that is same then port number.
@@ashutosh57 thank youu
Sunny do you have a paid training format? You explain so much better than any Udemy video and/or private class.
how to calculate root port ? for getting the root path ?
1:50 did he mean B is a bridge between A and “C”?
Thank you for your great works...
Which root will be taken if the cost DBA = DCA?
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.
Thank u Sunny
You are so welcome!
i understand the selection process but i dont understand why switch C has a designated port on a link that is inactive anyway. Why do these inactive links still require a designated port?
These inactive links are temporary. We consider them as back up. In case active links are down, they will be up and running. That is why they still require designated port.
