Try ospf cost <a high number for ex. 9999> on the BRI interface...

Do you have any other routing protocols being redistributed on either
router?
Did you try reseting the ospf process after applying the demand-circuit
command?
I have run into this problem and I do not recall exactly how I fixed it.

Subject: OSPF Demand-Circuit Oddity (How do I keep it quiet)
Gang,
I cannot make the demand circuit stay quiet!
I'm probably a little clueless and probably cannot see the forest because of
the trees. I configured an ISDN connection between two routers, R5 and R6.
It is configured so only R5 can call R6. There aren't any dialer map
statements on R6 for it to call if it wanted too.
Packets destined for the OSPF multicast address 224.0.0.5 continue to bring
the line up after I configure the interface as a demand circuit?
I tried the usual, no peer neighbor route on the interface to eliminate
feedback from an classfull protocol.
I then thought I must be missing something somewhere an began to shut down
the interfaces on R5 one by one to eliminate any feedback?
After I shut down every interface except for the BRI, it sill won't stay
quiet!
What is the deal?
I have attached all of the relevant information below. Any help or clarity
is greatly appreciated. I'm stumped!!!!!
