Ospf network types

What OSPF network types beside broadcast has the DR/BDR election process?

Hi Daniel!

There are two OSPF network types that use the DR/BDR concept. They are the BROADCAST and NBMA (nonbroadcast/multi-access) network types.

Note that if you are using the NMBA network type - you must manually specify neighbors with the OSPF neighbor command.

So the network types that do not use the DR/BDR are:
Point-to-point
Point-to-multipoint
Point-to-multipoint nonbroadcast
Loopback
