Hey Ato,
I'm sorry if I didn't sound courteous. I don't mean any disrespect.
And, thank you for the follow-up info. I appreciate it.
You said below and the "on/off" part confused me,

Does that mean it doesn't matter if ilmi keepalives are turned or not in the
lab?
Unfortunately, I don't have access to rtr with ATM interfaces and an ATM
switch, so I'm not able to test this myself. Also, I know that lots of
things like routing protocols and Frame Relay LMI require keepalives but I
don't know when an ATM switch requires ilmi keepalives.
Thanks again. Tim
