If you are going to use the "ip ospf net" command on the interfaces with the
non-broadcast command, then you must define the neighbors with the "neighbor
command". However, I believe the better way to do this is to use the ip ospf
net broadcast command. Don't forget the priority command (ip ospf priority)
and control where you want your DR (at the hub, of course). Hope this helps.

Subject: OSPF over NBMA
Hi All,
I just started to practice on the CCCIE lab.
I have a problem with getting OSPF learned routes to the routing table.
i.e ospf neighbourhip is there, all the routes are in the ospf database,
but
ospf learned routes doesnot come to the routing table.
My toplogy is like this
