This what I get from a sample configuration at CCO,
it state the following:
" If the router is part of OSPF p2p topology(2 routers), then only one end of t
he demand circuit must be configured with the "ip ospf demaind-circuit" command
. However, all routers must have the feature loaded within the area and must su
pport the "ip ospf demaind-circuit" command. If the router is psrt of OSPF p2mp
topology (eg hub & spoke), only the multipont end must be configured w this co
mmand."
In another CCO tech notes:
" Only one side require to have the demaind-circuit interface command because i
f the other side is capable of underatnding demand-circuit, it automatically ne
gotiaties this capability in the Hello packet. If it is not capable of understa
nding DC, it ignores this option.
DC can operate in any network, but only p2p and p2mp will suppress Hello.
Hope the above help us to understand better...

Subject: Re: OSPF DDR (continued)
For anyone that is bothering to read my thread, I found "an" answer. I
don't understand it, but it works. The key was to changing the IP OSPF
network type on the BRI interfaces from point-to-point to point-to-multipoint.
After 4 hours on this one topic I don't really care why it works. However if
someone else should care to figure it out let me know.
Thanks,
David
