If you have an Ethernet segment with three routers that are running
ospf they will automatically neighbor because the default ospf network
type for Ethernet is broadcast. The broadcast type will neighbor and
elect a DR and BDR automatically. The non-broadcast type does not
neighbor automatically. You will need to configure neighbor
statements for all DR and BDR candidates. It is important to set the
priority to zero for those routers that you do not want to configure
neighbor statements for. This will insure that they are not DR or BDR
candidates. In other words, pick one to be the DR and set everyone
else as a priority zero (interface command ip ospf priority 0). Place
neighbor statements on the DR that point to the your other routers.
Since you must manually configure your neighbor statements you will
get what you wanted.
You will not establish neighbors when another router attaches to the
segment and you are not using OSPF authentication.
To answer your question¡..yes!
