I would suggest another debug command that might work even better. Try
debug ip ospf lsa-generation. This will also tell you which route
caused the link to come up without all the other stuff that comes with
the debug ip routing command.

Debug ip routing will show which route is being entered into table that
is
generating an LSA. This should be why your link is coming up. Once you
figure that out you can nail down your access lists and or put in no
peer
neighbor to not add the other end of your bri.

I guess my question really is... why is it sending hello packets when
they're supposed to be supressed?
