A quick question, I'm trying to run IS-IS over frame relay studying for my CCNP on a Cisco 1750 Ver 12.1,

The "Router isis" command doesn't put me in the router config mode, does it mean that ISIS is not supported on this router ?

I ran in to a similar problem myself in my studies a few weeks ago. You can tab the is-is commands but when you hit enter nothing happens.

You need a later IOS (12.3 I think)

Check out (search by product) to find out which release is most appropriate.

I hope that helps!

I quick question, do you have to pay to download the latest IOS ? Because I find it, but can't download it.
