Has the initial adjacency formed? OSPF will keep bringing up the link until
the adjacency forms and both sides are aware that the line is a demand
circuit.
Is your topology changing? OSPF demand circuit will bring up the line if
there is a topology change. Is the router also a redistribution point?

ISDN, OSPF hello packets
I am having a problem with OSPF hello packets bring up my ISDN link. I
thought if a link is configured as demand circuit, OSPF Hellos were
suppressed but the hello packets keeping the link up.
My debug output:
*Mar 7 09:50:40.750: Di1 DDR: ip (s=1.1.35.5, d=224.0.0.5), 76 bytes,
outgoing interesting (ip PERMIT)
The Dialer OSPF commands
interface Dialer1
ip ospf cost 800
ip ospf demand-circuit
no peer neighbor-route
no cdp enable
