Free CCNA | Spanning Tree Protocol (Part 2) | Day 21 | CCNA 200-301 Complete Course

When Jeremy has a birthday party, everyone keeps buying him Cisco industrial routers. When he unwraps it he pretends he never got one before to make you feel happy. After the party he places each atop the stack in his closet. You would think he sells them off, but actually he keeps them all safe and in perfect condition, and he knows the MAC address of each one.

Great content

Really grateful for the videos!

I'm following the official Cisco Netacad course along this one and there is no mention of the PVST+/STP MAC addresses, so hopefully we don't need to memorize them for the exam

what can i say except you wellcome

When every u say "you no need to worry about them now, these are advanced topics" i am getting so scared.

hey Jeremy , thank you so much for your videos . I am new to networking and the way you explain the different protocols make it so easy to understand . I will continue to reference your videos . I'm scheduled to take my test and I cant wait to type in the comments I passed .

What is teh deferent between ExSim and NetSim?

What would you recommend for a job that rarely utilizes network engineer type roles? I'm often solving desktop tickets and end up forgetting a lot of what I learn quite fast. Any recommendations from anyone helps. Thanks

+Plus

For quiz question 9, wouldn't the answer be 130 since the port is 0/2? I' pretty sure in a previous lesson you mentioned that default port priority is 128 + port number.

The more I have been watching your video the more I am being debt to you. Thanks, my professor.

this is the hardest part of CCNA, very good explanation though

Best CCNA Course I've Ever Seen

Amazing, thank you so much for all your efforts,

Hi Jeremy, brilliant content. Question: is there ever an incentive to not use BPDU Guard on a port if it is an available option? Thanks again.

Anyone can clear my doubt on Quiz 10? As Root Guard and Loop Guard also serves the same purpose by shutting the ports down to get loop free environment

Judging by the comments, viewers seem to agree that Jeremy should be an author instead of a network expert... Personally I'd rather hire him as a network administrator and be extremely condifent he will always have things under control, and pay him a fat salary. That is, IF I was a someone with a business empire...which I am not 😂 far from it

Loooove this video

can we get slides for notes

hey Jeremy, it seems like the files on the google drive are scattered as I cannot find the practice labs for stp

Hi Jeremy, Thank you for sharing this. I just wondering if i can have all of these slices. thank you

Hello Jeremy and thank you for the video, quick question about the 0x8002 Quiz 7 part, should it be the first 4 bits ("8") as the priority and the rest (002) as the port number? 4 bits and 12 bits and a total of 16? thank you in advance

I like your video of CCNA, it is helping to understand networking

Thanks for YOUR help❤

Hi Jeremy,

If I have for example:

SW1 PRIORITY: 24576 (ROOT)
SW2 PRIORITY: 32768
SW3 PRIORITY: 32768

I set SW2 as ROOT PRIMARY, but SW1 priority is 24576, so SW2 set priority to 24576-4096 = 20480

The topology is now:

SW1 PRIORITY: 24576
SW2 PRIORITY: 20480 (ROOT)
SW3 PRIORITY: 32768

After I set SW3 as ROOT SECONDARY. In this case the priority is 28672 by default.

The topology is now:

SW1 PRIORITY: 24576
SW2 PRIORITY: 20480 (PRIMARY)
SW3 PRIORITY: 28672 (SECONDARY)

But SW1 has lower priority than SW3. What happen?

Thanks

is there a confuse about root/designated port remain stable in forwarding state, the following video show root port only receiving BPDU but not forwarding

In 2007, I passed my CCNA exam. in 2023 I understand what is CCNA........... Lol😄

Hi Jeremy,could you please tell me how does an interface learn a mac address in learning state from regular traffic but it cant receive or send the traffic ? thank you

Thx Jeremy for the video

Great work Jeremy!

Both BPDU guard and Loop guard sound the same

I'm deeply grateful for your videos, Jeremy. Thank you!

❤

Hi, the link for flashcards-lab doesn't work. I wonder if one of you have a solution, including Jeremy.

comment for algorithm

Hi Jeremy

pls which takes higher priority in determining the root bridge

root primary command or the priority command?

Hi, Jeremy!
Thank you again for this great videos. I want to ask you a question about Loop Guard protection. How a port may malfunction in a way that may forward normal traffic but not BPDU's?
Do BIDI optical transceiver may cause unidirectional link loops?
If another switch will stop working in the topology, in between the switch that the port is moved into the STP loop-inconsistent blocking state with the root switch; do the switch with STP loop-inconsistent blocking state port will also go down, because it lost the connection from it's root port and it's other port is in loop-inconsistent blocking state?
I also think that it might be to do a video or lab on the topic loop guard would be easier than to answer my questions 🙃
Thank you very much!

GOD BLESS YOU BRO.
