There is also a nice explanation on the DocCD regarding the different OSPF
network types:

"You can block OSPF flooding of LSAs two ways, depending on the type of
networks:

On broadcast, nonbroadcast, and point-to-point networks, you can block
flooding over specified OSPF interfaces.

On point-to-multipoint networks, you can block flooding to a specified
neighbor."

Oh. I wish I could honestly say that I remembered that!
____

ip ospf database-filter all out

Usage Guidelines
This command performs the same function that the neighbor database-filter
command performs on a neighbor basis.

neighbor database-filter all out

Usage Guidelines
This command performs the same function that the ip ospf database-filter all
out command performs on an interface basis.

I guess there's a little bit more to the story! Imagine that...

You need to change the ospf network type of all neighbors to
point-to-multipoint and then use the neighbor command.
