Hola Vid..
Look at the OSPF interface Types (show ip ospf interface), maybe you
can find there the problem
Also a good command is debug ip ospf events
You would see what is happening, BTW FR == NBMA / so it's not a
Multicast interface try in the hub on router ospf process, using the
neighbor command
You should have a good time playing with those commands..
