Spanning Tree


Since starting this blog here, I'm going to continue from where I left off with my studies.
I've been looking into Spanning Tree for the last few weeks and there are so many topic areas to cover. I am not accustomed to writing blogs and I've been rereading what I have written multiple times so hopefully not too many mistakes here :)

I'll try and keep information short and sweet.

Let's start!


IEEE 802.1D is the standard for Common STP
It's labelled as common as uses a single STP instance to carry all VLANs.

STP is required to prevent loops/broadcast storms from occurring when you have redundant links between switches. Prevention is done by STP port blocking.

In Spanning Tree, lowest number wins.
