- čas přidán 18. 08. 2024
- In this video, we analyze an STP Topology with varied costs. Learn about STP, RSTP, root switch, root port, designated port, and more in this in-depth interview review. Perfect for CCNA students and those looking to improve their networking knowledge!
Today’s topic: Spanning Tree Protocol Concepts w/ Port Roles and States
Today’s Interview Theme: Predict the STP Topology of a LAN and Explain Why
This video sets up a technical interview scenario with a set of questions. The questions revolve around LAN switching, as discussed in the video linked just below. Your job:
1. Watch this video until you understand the scenario.
2. Pause and answer for yourself.
3. Watch the rest of the video to hear what I would be hoping to hear from you in a technical interview.

This follow-up "Interview Review" is really helpful. Thanks Wendell!
Sure thing, my friend.
Brilliant exercise that cleared many concepts .thanks
Great to hear, Sana!
I really enjoyed practicing this interview. Thank you for sharing it with us.
You're quite welcome! (I like these, too.)
This is a fun way to test one's understanding on a topic. It would be great if we can be tested on STP topology with multiple links between switches. Thank you for the video.
That's a great idea! The final section of that chapter (Vol 1 Chapter 9) discusses EtherChannels, which are the primary solution to the mess STP lands in with multiple parallel links between switches. When I circle back to that section, that may be a great place for an interview review like that. Regardless... great feedback, much appreciated!
And you're welcome as well.
Thank you for the excellent content, Wendell! I know it's not strictly related to the main objective of this channel, but I'm sure I'm not the only one who'd love to see a home tour of all the cool geeky hardware you have at home! :) Have a great weekend.
Well, I appreciate the request! Now let me find time to clean up enough so my wife would let me post it. :-) Maybe one day!!
Just imagine a 6' rack of routers and switches in the unfinished basement on the other side of the wall, just past my right shoulder... :-)

Thank you! :) Yes, a rack taller than me full of networking devices is an interesting thing to imagine! :)
Any links connecting to the root switch and another switch the root switch always wins -- UNLESS -- That switch you are connecting to the root switch has a lower bridge ID and then a new election will make the new switch the root. Please correct me if I'm wrong
Scorpio,
If I understand your scenario correctly: Correct.
Restated: SW1 is root. A link that did not exist came up, connecting SW2 to SW1. Whichever of the two has the lower BID wins the root election.
