Getting to ISIS router config

Hi.

Im having problems getting to the actual router config mode when trying out IS-IS. On some images I have, its not supported, but on at least two images, (i suspect you need IP Plus to have IS-IS support), when i type "router isis" it doesnt go into (config-router) mode, but just stays in global config mode, without giving me any reason why.

I think im missing something critical here

Here, check this out. It will tell you which IOSes support what.

Thanks. I did, It just seems confusing to let you type in the router isis command one image without complaining, and on another it will tell you that the function is not supported.

Thank you Meister

No problem. I have come across a few "interesting" things in the IOS while studying. For instance there was an issue with using a certain part of QoS on a 3550 switch that I came across recently in my school's lab. There were a few different 3550s all with the same IOS and some would take all the QoS commands we would throw at them and a few of them would come back with the "unrecognized command". Turns out that it was a hardware thing between the different models of the 3550 series that would allow certain features to be used and others not.

Don't remember the commands or the exact model numbers though.

I was unable to get my real hardware to run ISIS, but using the following image
c3640-jk9s-mz.124-16.bin (which was actually too large to fit on my 3640 32/12

I was able to run all labs from the lab book via GNS3/Dynamips.

Hope that helps.
