For straight integrated isis ( ip only, no ISO crap ) things can be set up
with just a couple of commands.
For those who haven't done IS-IS, it's a little unusual for those coming
from RIP or EIGRP or any of the IP routing protocols. But in general, one
can quickly get something up and going by doing the following steps
Router isis [ area tag, which appears to be optional ]
Net something and here is the weird stuff. The format is highly unusual for
us Cisco jocks.
So in my case, 49.0001.router i.d. in the format of aaaa.bbbb.cccc
.00
This RID ( if you will ) must be unique to each router.
The first part - the 49.0001 is the isis area id. I believe that
actually the first two numbers indicate something other than area. Still
have some reading to do.
Is-type level-1|level-2|level-1-2
Then on each interface one must enter the ip router isis [area tag, if one
used it in the router process setup ]
There are a wealth of commands within isis, but most appear to be relevant
only to CLNS / ISO rather than native IP
I can see where Cisco would throw something like this on the CCIE Lab just
to mess with your mind At first glance it would appear that IS-IS is
completely alien to the ip protocols, as implemented in the Cisco world.

Can you enter any commands beginning with clns in global configuration mode?
I dont know really anything about isis, but it looks like there is a 'clns
routing' command that must be entered in global config mode... maybe is a
feature set issue.
