The network+ -> CCENT debate has been mentioned plenty of times here on the forum but if your leaning to Cisco, here is what I did. Fresh out of network+, I spent an hour or two at the local Barnes&Noble. I read through a couple of chapters of a textbook for ICDN1 to get an idea of whats in store. It is a perfect tie into ICDN1 (others would argue superfluous) If you feel that..."thirst" for more, you'll start putting the theory into action.
