Re: IOS downgrade!

[Philip Smith <pfs at cisco.com>]

Hi Benson,

Why would you want to downgrade from 12.0 to 11.0? You will be going back 
almost 5 years in IOS development, and I can't really recommend that.

Anyhow, assuming you have a good reason for doing this, if you have access 
to the older IOS image you want to run, you simply need to install it in 
the router FLASH (you didn't specify which platform), and then add it to 
the boot system sequence. If you can give me the name of your current 12.0 
image, the new one you want to run, what router you have, I can let you 
know the exact command sequence you need.

One resource which is useful for all ISPs is IOS Essentials - there is a 
section in there which shows you how to do image "upgrades". Check out:
http://www.cisco.com/public/cons/isp/documents/IOSEssentialsPDF.zip. (It's 
900kbytes big, BTW.)

HTH,

philip
