Chris,
CLNS is OSI service for CLNP (their layer 3 routed protocol that was to
compete with IPv6). ISIS is OSI's routing protocol (that competes with
OSPF). ISIS was initially designed to route CLNS traffic, but also works in
an IP environment.
CLNS has been removed from consideration in the R&S Lab, so only an IP
environment is needed. ISIS will work in an IP environment, so don't set
global "clns routing" when you use ISIS. If you want to run ISIS over frame
relay, you need two map statements, the standard "frame map ip x.x.x.x 502
broadcast" and "frame map clns 502 broadcast".
HTH, Kym
