My home CCNA lab consists of 3x 2501 routers w/ 16/16 and 12.2 IOS plus I recently acquired a 2620XM router with 12.3.t-something code.
I've heard the current CCNA exams are based on the 12.4 IOS. Can I even consider runing 12.4 on my old 2501s?
ALSO - my 2620XM has 2 WIC-1DSU-T1 cards. How do I use those? I mean, do I need to plug any device into the port to be able to configure it? I did order 2 WIC-1T cards for serial interfaces...
I don't have access to any IOS images unless I can talk our NOC folks in another part of the country to help me out.
And, what are the major improvements in 12.4 vs 12.2? I noted on my 2620XM router it won't let me designate point-to-point or multipoint on my subinterface configurations.
