Anyone have any good analogy's for STP/RSTP Concept...?? The ICND book explains it over too many pages

I havn't seen too many people complain about STP questions on the exam, maybe I am stressing too much

Try writing all the valid information, you will see that the ideas behind it are pretty easy and alot of that information in that chapter is filler. My notes for those are only like 1 page!

BTW what book are you using?

CCNA ICND Ciso Press Self Study Book....Its not that bad, I just need to re-read things constantly to get the picture in my head clearly. Writing diagrams and notes on an extra large white boards a lot as well!!!

STP is the protocol which prevents layer 2 loops in a switched network. It designates which ports on the switch should be forwarding and which should be blocking in order to eliminate any loops in the network. Loops causes broadcast storms and flooding etc etc. Loops are caused by redundant links in a network.

RSTP is Rapid STP, its works the same except it incorporates all the extra features that stp but does it faster and easier

hope this helps

In laymen's term, RSTP does not need to use the "Listening" state like STP.
Convergence time happens in a blink of an eye with RSTP instead of 30-50 seconds a device with STP.

I know one switch is designated as the "Root Bridge". A switch becomes the root bridge by its priority and MAC address. There is a default number for priority but I couldn't exactly tell you what it is. I think its 32 thousand and some change. Anyways, it pretty much whoever has the lowest MAC address unless you change the priority. Once the root bridge is picked all the switches in the same network will fall in place in hierachal format under it.
