Hi,

These days people only have OSPF interface type as point-to-point and
broadcast. I understand that NBMA was required for technologies that
inherently dont support bcast, but where packets need to be sent to
multiple nodes (like ATM).

Given that ATM and Frame Relay networks are mostly out, when would we use
an OSPF interface type as NBMA or point-to-multipoint.

Is it in some wireless domains that we will use this?
