I will have to look into the answer for you. But this is the issue: When
you use ILMI the full NSAP address of the edge device gets registered
with the LS1010. Therefore, the LS1010 has full knowledge of the ATM
devices in question and can setup the call. Without ILMI you will have
get NSAP information into the LS1010 somehow.

Well, Mark you say you aren't sure what I am trying to achieve - Julie
Ann
was right - a fuller understanding. As I mentioned in another e-mail,
Marc
from CCBootcamp recommends that this particular technique be known, and
as
you say this may be required by the setup that they give on the ls1010.
It's like setting up LANE without a lecs (yeah, I know a lot of people
think
it's not possible (look back in the archives or I'll post the config &
output of a LEC not using a LECS)).
Now, probably 999 times out of a 1000 the above wouldn't be required,
but
that,as we all know, is what a lot of the scenarios on the lab exam want
(things rarely seen in the field). BUT, by asking about these off the
wall
things, Cisco are really testing the true depth of our knowledge.
So, any solutions? (Astound me with you knowledge!)
