I am wanting to pursue my CCENT/CCNA cert this year (haven't decided if I'll start with just the CCENT first or take both tests at the same time, still weighing my options) and I've started to piece together a lab.
So far, here is what I have come up with:
2511 router to be used as an access router (for consoles, got this one as a freebie!)
2621 router (also got this as a freebie!)
2950 (en-route to me, haven't received yet)
I'm thinking I need at least two more routers and maybe another switch but I was unsure of what to look for. Price is definitely a concern, if I can find routers for under $100 that would be ideal.
Another question I have is material. Can anyone recommend decent study material and lab guides?
This seems like a great forum and I have only recently stumbled across it a couple of days ago. Thanks in advance for any replies....
