Alright...this took a little more time than I had hoped, but my initial GNS3 lab is done. I designed this initial lab to test through most of the Cisco CCENT concepts. I'm planning on posting this on the Network World blog I'm running this month tomorrow, but figured I'd post it here first. The GNS3 topology is using a 2600 series router / image (I figured many people could get ahold of one of these images either via a SmartNet contract or Ebay). The exact image I used is c2600-i-mz.123-26.bin.
The lab itself isn't as pretty as I'd like, but I primarily wanted to get something out there with a template to create other labs.
