Ok, a few things..
#1. In a hub and spoke network, everyone establishes a neighbor adjacency
with the hub only. Remember that OSPF packets have a TTL of 1. That would
prevent your spoke router from ever neighboring with the other spoke.
#2. You should always set your OSPF priority highest on the hub router. In
fact, I set the hub router higher (say 200) and the spoke's, I set to
priority=0 (Don't participate in OSPF DR elections). That way, you have
full control over who the DR is always, without any doubt, given that the
CCIE lab will try to mess with you in every way possible. More control is
always best in the CCIE lab. Leaves little room for doubt.

Subject: OSPF over Frame Relay non -broadcast networks using neighbor
command.
I have a hub and spoke frame relay network running
ospf. I am having problems getting the neighbors to be
fully adjacent with each other. The hub router becomes
full with each of the spokes and the spokes become
full with hub but I cannot get the spokes to become
full with each other. I have a "neighbor x.x.x.x"
command on the hub for each of the spokes and and I
have the same commands on the spokes for the hub and
the other spoke. When I do a show ip ospf neighbors on
the spokes I get the folling:
For the other spoke I get a Priority of 0 and State of
ATTEMPT/DROTHER. Is there something else that needs to
be done in order to get the two spokes to become
adjacent with each other?
I have the broadcast command at the end of my frame
relay map statements and I can ping from spoke to
spoke. I don't want to use the "ip ospf network
point-to-multipoint" or the "ip ospf network
broadcast" command.
Thanks for any help that you can give me.
