I created this video because I wanted to explain WHY root bridge placement is so important from a Spanning Tree(STP) perspective. There are lots of videos and information out there about STP, but I haven’t found one that actually explains why the location of the root bridge is important. Hopefully this is beneficial.
As a pre-requisite, you will need to be familiar with what STP is and how the root bridge is elected and a loop free path is created. The following videos do a pretty good job of explaining it:
STP Basics: https://www.youtube.com/watch?v=uIr3u9bXESo
STP Root Bridge Path Selection: https://www.youtube.com/watch?v=y-SppCHx1Qs
I also included these links in the video description on YouTube.
Great video! Thanks for bringing in some real world scenarios. In that scenario with two core switches, would it be ideal to have a connection between the core?
Yes. I just forgot to include the link between the two in the video. In that case, it may or may not have been disabled with STP in play. Oops!
Nice job!
Great video, Matthew! I think it’s a common misconception that all L2 traffic flows through the root bridge.
A very common misconception indeed. “Some traffic”, but not “all traffic”.
Aloha! Great job Matt 🙂 Cheers!
Mahalo Matt! Hope all is well.
