ISDN config (maybe a simulator problem?)

I guess I'm just looking for a reality check here, or at least some closure ;-)

I've got R1 connected to R2 via bri0/0 with a basic-ni1 simulator and spids. Everything seems to work great save that traffic never seems to go across. Attempting to ping the other side brings up BRI0/0:1 but OSPF never forms an adjacency, it just times out after the idle-timeout and drops until the next ospf hello to 224.0.0.5. I've stipped all the fancy configs from the interfaces, but no change. The interface shows packets in and packets out. Then I tried to ping the router's own BRI interface IP and it cannot (is this normal?), so I'm like is GOD telling me to go drink on New Year's Eve?

but seriously, this has got to be just a simulator problem, right?
