Just remember a few things - OSPF Network Types should
be compatible.
ie. P2P and P2M are compatible
Br and NBMA are compatible
Remember which ones have DR elections and which ones
do not.
Use of priority to influence this is common - an
interface with "ip ospf priority 0" will never try to
win the election and become DR. One with 255 will
always win (unless you do it on two - but why?).
Hmmm...
You can set the ip ospf network type but do not always
need to - what if you are told you cannot do this -
remember they will likely take something away before
they ever give it...
Keep these things in mind...
Always ask yourself:
Is it a P2P interface?
Is it a Multipoint (or logical subinterface)
interface?
Is is a Brodcast interface?
Off the top...
