Router and IOS versions:

Hi guys, anybody know if it's possible to load the latest IOS software versions on to older cisco routers.

Basically iam a CCNA student and want to buy a cheap cisco router, and load the latest IOS software versions (12.3) (12.4) on to it, so I can practice using the latest commands.

So is it possible to update or load the latest IOS software versions on to older cisco routers?

Cheers Sam...

Re: Router and IOS versions:

Hi,

First, check the router "End of software maintenance releases" and "Last Mainline Support" from its EOS Announcement. Second is the size of MEMORY and FLASH as there could be IOS that can still be load to your router but depends on it installed MEMORY and FLASH.

Some 2600 series routers can still suport 12.3 mainline but not 12.3T or 12.4 mainline and beyond

Regards,

Dandy
