OSPF Network Types are very important in OSPF. OSPF Protocol uses different OSPF Network Types. Some of these Network types are Standard and Some of them is Cisco Proprietary. So, what are these Network Types?
Mainly,these OSPF Networks Types are given below:
As you can see, some of these network types are standard based and some of them are Cisco proprietary. Standard ones can be used in all vendors. But the Cisco proprietary types are used only with Cisco products. Now, let’s explain, each of these network types with entwork diagrams.

Broadcast Networks is the mainly used OSPF Network Type. It uses Multicast and Broadcast to reach multi endpoints. This is a very useful network topology for an OSPF design.
DR and BDR selection is done for Broadcast Networks.
Nonbroadcast Multi Access(NBMA) Networks is basically an simulation of Broadcast Networks. Each neighbour connect eachother as unicast and all OSPF packets are Unicast.
OSPF DR and BDR selection is done for Nonbroadcast Multi Access(NBMA) Networks.

As we can understand from its name, Point-to-Point Network is one of the OSPF Network Types that provides connection from one end to another end. There are two nodes and the communication is between these nodes for a single Point-to-Point connection.
OSPF DR and BDR selection is not necessary for Point-to-Point OSPF Networks and so it is not takes place.
