Hi!

to complete your information in the post:

ip ospf network point-to-multipoint : neighbors discovery is enabled and DR & BDR is automaticaly established

ip ospf network point-to-multipoint nobroadcast : neighbors discovery is disabled, and DR & BDR must be manualy configured

ip ospf network non-broadcast is the default type used in serial interfaces but when frame-relay multipoint interface type is in use, in this case ip ospf network point-to-multipoint is used by default (with neighbor discovery)
