You just explain the most complicated concepts so simply Sunny. Stay humble and the best teacher eva! It would be great if you could have a video for EIGRP...please please
I would elect you as boss Sunny! Thanks for the simple explanation.
Wow, thanks!
I have never seen such a teacher, everything you teach is absorbed with no hustle!!!
This is just the best explanation I have gotten about STP in years. You demystify it sincerely
I love how simply and succinctly you explain all the topics! It is very helpful! Thank you!
Excellent instruction as always. Thanks!!
what a marvelous explanation!!!! Thank you so much
Very clear explanations Mr. Sunny !!
Thank you! Please continue making videos, they are extremely helpful.
Thanks for the video, Sunny!
u make it easy to understand. Thanks, Sunny.
Great video Sunny. Nice production values, your graphics make it easy to follow what's going on
Thank you very much! It helped me a lot.
Very clear teaching. Simplicity to the eye. You also have a clear, friendly tone in English. Thank you very much Sunny.
You are welcome!
God of explanation. Thank you for this Mr. Sunny!
Glad it was helpful!
Hi Sunny, I follow your videos 2 years ago and you always make me happy to understand many things about network. I appreciate it so much. Stay humble. Hope I meet you someday.
Sunny explains STP election process better than my university professor:)
Thank you very much!
Very helpful, thanks.
Always enjoy your videos
Thank you very much, Bob.
GREAT-GOOD TEACHER
Amazing,,,,, Amazing,,,, Amazing!!!!!!
GREAT!!!! THANK YOU!!!
I like your easy going style and the presentation of your videos. Your videos helped me sort out some information, I now have my CompTIA Security+ Certification. The next certification is Certified Ethical Hacker (CEH) exam at the end of July. Thank You
Sunny is the best instructor
Thanks you for watching!
I'm currently studying for the new ccna 200-301. Whenever I encountered topics that I don't understand in cbt nuggets, I go to your videos. I don't know why but it feels like the way you simplify/explain things was easier to understand :)
Thank you for your compliments! I am glad you find my videos!
U should do the boson practice exams too. i like sunny too
you are the best, and rocks.
Thanks a lot, Hassan!
Great vids
So nice explanation, I can't explain in just one word or one line even in one page.
Heartly thanks sunny
Very Good !
Thanks!
Hi Sunny. I love your style of teaching. I'm learning loads! Any plans for some videos on VTP and Vlans? I'd love to see how you explain these.
I will soon by this month. Stay tuned. Many thanks for your trust.
Great
For me ACLs, Extended and Named, are difficult to understand. I've used other tutorials but they always make it seem so complicated and I end up wasting my time. Sunny, I would really like to see how you teach Access Control Lists. It would be much appreciated.
your the best
Thanks!
Really nice video
Glad you liked it!
👏👏👏👏
7:02 your tutorial videos are great, as always. However here you fall short of explaining how designated ports and blocked ports are determined.
Thank you so much for your courses ! can you pleas tell us the name of the tool you uses to create courses ? thanks so much
What I'm interested in and is not explained in most STP election examples is how it looks in a more complex topology with acces, core, ... switches and how it looks like in the STP table. My particular question would be if Switch C would only be connected to B (so it's A -> B -> C), what would be the Root Bridge from the perspective of Switch C? In this scenario is Switch B the root bridge for C, or does C also see A as the root bridge.
TLDR: Does root bridge selection work over several hops or just direct links to the next switch(es)?
Hi Sonny, I enjoyed watching your videos as difficult terms are simplified. I have a question regarding STP designated port election. On cisco books it says that the DP on each LAN segment is the switch port that advertises the lowest-cost hello in the Lan, which mean the port in the switch that has the lowest cost to reach the root. On the other side the video says the DP port on a segment would be the port which switch has the lower priority. Can you please confirm which is true, as it confusing.
Thanks!
Lowest cost and lowest priority are two different things.
LOVE your videos! Got a tech question for you that no one seems to be able to answer. Does the root bridge move with every new message because the end device's proximity to the switch changes with every message?
I THINK I've got it figured out. The root bridge is decided arbitarily but definitively without regard to the proximity of the source or destination device. Then duplicate routes which could cause loops are shutdown as alternates. If the root bridge (bridge being an antiquated term for switch) proves to be suboptimal on a long-term basis (and NOT simply because of the proximity of the end devices involved in a particular transmission) then the switches can be manually configured to produce a more optimal root bridge for long-term operations ...I think. The concept of route cost is NOT related to one particular transmission but rather to establishing a somewhat arbitary system long-term system which on occasion may prove less than optimal in particular instances but overall is fixed and works well MOST of the time. The concept of cost is just used to make the somewhat arbitary system somewhat efficient and clearly defined.
How is link cost calculated, probably as a function of number of hops and link speed in each hop? Also, since BID is priority + MAC address, does a multi-port switch have 1 BID or multiple BIDs, one for each port?
What happens in a network with unmanaged switches?
It doesn't work with unmanaged switches.
at sec 0:52 what about Extended system ID? i am asking bcs in last video when u set up priorities you used 32768, but it should have been at least 32769 bcs there is no layer 2 device without at least a default vlan where spanning tree is configured for.
What do you mean 'superior', do you mean lower ?
