This Cisco router and switch kit includes everything you need and supports all the features to pass your CCNA test. It comes with two 2500 routers and one 2610 router. The 2500s will be maxed out on memory at 16/16 and the 2610 will be maxed out at 64/16 so you can support IPv6 for the new exam.  The 2521 will act as your frame relay router.  The 2520 will act as an Ethernet router and in other labs can also act as a second frame-relay rotuer.  Then we add in a 2610 so you get exposure to a modular router in the 2600 series. Our kits have console kits, serial cards, back to back cables and the latest IOS software. You will also receive one 2924 switch which supports 12.0.05 and two 1924 series switches.  No one else has our copyrighted 224 page CiscoKits Self Study CCNA Lab Workbook(see the lab topics by clicking the link) that will walk you through 60 different labs! Why spend hundreds of dollars on a lab kit if you don't have the labs to accompany your equipment? You will also get our CiscoKits CCNA/CCNP Test Engine with over 500 different questions. Not only that, but you will also get CCNA test tips, the IOS on CD, Cisco's TFTP Server and other prep material.  There is also more!  You will also receive our CiscoKits CCNA CRAM Sheet.  This six page, full color, laminated foldout is a great addition to your CCNA Study arsenal.  These routers are in excellent condition and are guaranteed working! The extra information provided on CD is worth $200 by itself. You will be provided with everything you need to hit the ground running to prepare for your test. No need to spend hours looking for tools, procedures, test review material or fumbling around looking for labs. This is a great educational lab kit. Software licensing is the responsibility of the buyer and is provided on the CD only as a backup of what was loaded on the router when we purchased it.
