Hey Rob
ip ospf demand let only the ospf neighborship in state full, even no hellos
goes over the link, as long as no ospf topologies occurs. An ospf demand
circuit belongs to the link and not to one interface, both router treat also
this link as a demand-circuit link. So, both router could start the call,
even if only one side has the cmd ip ospf demand-circuit.
Callback and ip ospf demand works fine together and makes sense.

Betreff: Does it make sense to configure isdn callback and ospf demand
circuit?
Hi all,
I've been playing around with ppp callback. I've gotten the ppp callback
portion to work correctly. However, when I add callback to my ospf demand
circuit config, the demand circuit stops working.
Logically, it makes no sense to configure both because, to me, callback
takes advantage of cheaper dialing rates. If that were the case in real life,
then why bother with callback at all. Just configure a demand-circuit with a
dialer map on the side with cheaper rates.
But, in this lab scenario, I'm trying to both to work together with no luck.
I see that IPExpert's lab 20 has both configured?
Any ideas? Thanks,
Rob
