Hi,

you asked if we can install more than one not if it was something useful in real life.

actually i want to know about it... that what is the benefit if we install 2 IOS in router.

[cadet alain]

I don't see any benefit as you can only use at once except maybe for testing a new IOS before deleting old one.

In my experience the main reason to have 2 versions of IOS in flash of the router is indeed so that you can test a new version of IOS and can fall back easily to the old version if there is a problem with the new version.
