Hi,
This is actually folklore :-) ISIS uses its own PDU's and borrows some
ES-IS hellos, but doesn't use any CLNS PDU's for operation. Turning on
CLNS routing enables routing for CLNS, nothing more. You don't need it at
all for IP routing with ISIS and I think newer versions of IOS reflect
this. When you do add it, you tend to change the output of a few show
commands.
