I did a test in my home lab with three routers. Two configured as OSPF routers, the third one as frame-relay switch.
In every test I booted up the two OSPF routers, entered two debug commands ( debug ip packet detail, debug ip ospf adj) then booted up the frame-relay switch to obtain the debug output. The deubg outputs show :- (a) For Point-to-Multipoint network type (using the interface subcommand ip ospf network point-to-multipoint) - Hello packets were exchanged using multicast during the Init-state - OSP packets were sent using unicast during the ExStart, Exchange and Loading states - after Full state, hello packets were sent using multicast (b) For point-to-multipoint non-broadcast network type (using the interface subcommand ip ospf network point-to-multipoint non-broadcast) - Hello packets as well as other OSPF packets used unicast duirng Init, ExStart, Echange and Loading states. (c) Point-to-point network - Hello packets as well as other OSPF packets used multicast during Init, ExStart, Exchange and Loading states. The debug outputs too long to post here but I can e-mail separately to anyone who wants to look at them.
