Koliy: You can have OSPF network mismatches where the adjacency is
established but there will be no LSA transfers. Both point-to-point and
point-to-multipoint use multicast for hellos but the point-to-multipoint
network type uses unicast for LS updates and the point-to-point uses
multicast for LS updates. Changing the hello timers will not fix this
mismatch - you must have the OSPF network types match. Use debug to see
where the transfer hangs. Do the obvious and change the spoke
interfaces to point-to-multipoint, or leave all interfaces as the
default non-broadcast network type. For the default situation you will
want to have the hub as DR and use neighbor statements.
