what feature set has isis

[rjackson]

I am trying to learn isis. My routers are running ip plus and it accepts the router isis command without error but does not enter router config mode.

What feature sets support isis?

You can use the 'Software Advisor' application from the TAC Tools menu to check this. On the 2500 router, it required Enterprise or Service provider. I suspect this is the same for all platforms but I would check for your specific hardware.
