How does the root in spanning tree protocol works?
I am studying spanning tree protocol attacks and I would like to understand a thing. The root is on the "top" of the tree, how can we exploit this to put in place an attack? We can, in some way, become the root, but what privileges would we get doing this? I don't get if the root can read all the packets, because I thought that if two host are connected in a "sub-part" of the tree, the root doesn't see any message, or am I wrong?
So it would be useful just because I have more chances to read more messages but I will never see ALL the messages, right?
Another thing, how can I put in place an arp spoofing attack being the root?
