Hello Michael.
I refer to yout @ReneMolenaar’s previous post where he states that [quote=“ReneMolenaar, post:24, topic:921”]
They all work so it doesn’t matter too much which [network topology] you pick.
The point-to-point or point-to-multipoint network types are probably the easiest to use. You don’t require a DR/BDR election so you don’t have to worry about setting the correct priority.

So it really doesn’t matter which network type you choose, as long as they are configured correctly.
However, keep the following issues in mind:
* If each area is composed of a point to point connection between routers, you do not require DR/BDRs at all.
* Secondly if you are creating four areas and these areas connect to each other in a ring topology, then one of these areas will not be directly connected to area 0. You will require either a virtual link (which is not advisable as a permanent solution) or you will need to revise the topology.
I hope this has been helpful!
