Some of the labs in CCNA 4 v3.0 won't work with the version of IOS we have on our routers. I have 2501 and 2514 series routers. I have IOS version 12.0(14) on them right now. I need to know if can get an update with out the contract. The school I attend does not like the CCNA program we have and won't give us the money for it. the flash file is C2500-D-L.
