OSPF Network Types : Broadcast/NB, NBMA,P2P
I would like to know, based on what criteria should I determine if my Network Type should be:
Broadcast, Non Broadcast, Point to Point, Multicast, NBMA,etc....
I have done some reading, but there is a lot of confusion.
Any clarification on this topic will be very much appreciated
Thank you

I believe Point to Point can be on Serial Link and it does not have to be encapsulated.
Broadcast is on Ethernet Network and it can be Point to Point and it can be Point to MultiPoint (Hub and Spokes)
There is also Point-to-Multipoint non-broadcast Network, I am not sure if this is on Serial Links or Ethernet Links?

Do you have a real-world use-case, or are you just asking for certification purposes, for example?
If it helps, on networks nowadays using standard Ethernet technologies you'd use point-to-point where you have a pure L3 link between two routers. You'd use point-to-multipoint where you have more than two routers on the same L2 segment using the same subnet.
If you're using WAN technologies between routers you might need to use NBMA but I'm sure the two I mention are the most prevalent these days.

Thank you Guys

Point to Point is when you have a Serial Link connecting 2 Routers and the encapsulation is HDLC or PPP
NBMA is used in Frame Relay and ATM networks
