It sounds an awful lot like the problem I had while using dialer interfaces
as opposed to physical bri interfaces. Are you using dialer interfaces? If
so, try a passive-interface on your dialer. If you are using physical
interfaces, search for "OSPF Demand Circuit" on CCO. There is a good link
that I have used for this very thing. Good luck.

Subject: ISDN - OSPF Demand Circuit

Hi All,

I have a bit of a problem, I have configured an OSPF demand circuit over
ISDN that just will not stop coming up even with the inclusion of the
command 'no peer neigbor-route'. The ISDN circuit is in OSPF area 0 as
are both attached routers.

I thought initially it may be IGRP being redistributed into OSPF causing
a change in its status but I have blocked incoming IGRP routes by
setting a 'passive interface' on the sending router with no luck. 'Show
dialer' reveals the reason for dialing as '255.255.255.255' - a
broadcast. The interfaces are both point to point in OSPF however and
not broadcast.

Thanks for your advice.
