What would be considered the root bridge of this diagram, for the spanning tree model.

Which one of the switches here in the diagram for spanning tree would be considered the root bridge, I know the general rule is that you first look at the priority value, if the priority value matches then we look at the mac address. How do we understand the value of a mac address, this is something that i have either missed or wasn't taught. I have general idea of understanding things like subnetting and the like. But mac addressing is kind of lost on me, not what it stands for. Just its value, and how to determine that value. Maybe i am looking at this too hard but, i was wondering if you guys could point me in the right direction, thanks!

Hi @curtisaguinaga758815924 ,

 

In this scenario, swB has a higher MAC, since its third bit group  is greater than the others, which start at the fourth bit group.
