OK just for clarification. There are a couple of training paths that are offered by Cisco. One is the Cisco Networking Academy Program. This program was mentioned above as being a four semester program training prep for the CCNA exam. IF you have the time and really want to lean the stuff I would recomend that path. Most CNAP school have a Cisco lab on site which comprises of 5 Cisco Routers and 2 Cisco switches. They allow hands on training for the entire course.

there is also Cisco Professional certification path which many of the 'professional' training center offer these course. There are week long or two week long programs for professional it is fast (really fast) paces classes as many of you are aware.

there are also many many many self-study book and the like that are avaiable. I used the Cisco CCNA exam prep, along with Transcender practice exam for my CCNA certification. I am also a Certified Cisco Academy Instructor.
