OSPF over Point-to-Multipoint - Discussion

Hello all :)

As you may gather, I am on chapter 12 of the CCIE practical studies book
doing the OSPF Labs.

I have one question.

I find that when running OSPF over a frame-relay point-to-multipoint
network, it is easier to run the "ip ospf network point-to-multipoint"
configuration on the hub and spoke routers rather than setting neighbors up
and setting the hub "ip ospf priority 255" and the spokes as "ip ospf
priority 0"

I personally do not like the way the configuration in NVRAM changes so that
you don't see the neighbor commands in the hub router configuration when you
set the spoke routers ospf priority to zero and so forth.

The question is (well two actually), 1. what is the preferred method and,
2. why would you use the neighbor/priority method as to the
point-to-multipoint method.

I fell that this is quite important to get right and study further before I
move forward :)

Many thx as always,
