Mike,
Frankly, I've never tried to get SVCs to work without ILMI.
What prompted you to try this? Curiosity or a hot tip that
it might be on the exam? ;)
I'm not exactly sure what's going on here, but here are some
thoughts.
(1) Check your text graphic below. You (allegedly) have
both r13 and r14 plugged into a0/1/1 on the ls1010. I
assume that r14 is really plugged into a0/1/0.
(2) If you have 'atm pvc 16 0 16 ilmi' configured, ILMI is
enabled. 'no atm ilmi-keepalive' disables ILMI keepalives,
but it does not disable ILMI. FYI, I think this is disabled
by default.
(3) Notice the output from 'show atm ilmi-stat': you are
getting a valid NSAP prefix from the switch
(47.0091.8100.0000....). The AA and BB addresses are not
showing up.
(4) You're learning OSPF routes over the atm interfaces.
What does 'show atm vc' tell you, both on the routers and
the 1010?
(5) The only 'registration' that I'm aware of on the ls1010
would be where you hard-coded ATM routes for your AA and BB
prefixes. Address registration via ILMI is on by default.
Try 'show atm route' on the ls1010 to make sure those AA and
BB addresses are getting in there.
(6) To really turn ILMI off, delete atm pvc 0 16 from your
routers and do 'no atm ilmi-enable' on the relevant ls1010
interfaces. In many cases in ATM where one side of a
connection is configured for option X and the other end is
configured for not-X, things just don't work right.
HTH,
Scott
