I had similar problem couple of month ago,,

When I did neighbor on only one side, it seems to work, until I reloaded the
router and neighbors went away,
 Once I put neighbor statement on both side, it came up even if I reloaded
the router,

I will put neighbor statement on both side, just be safe.

As you can see in example from Doc. CD, neighbor command is only used on hub
and no neighbor command on other router. I am having problem with adj. when
command is only on Hub router. what is correct way to configure point to
multipoint nonbroadcast, the way that works or the way that is documented in
CD ?

OSPF Point-to-Multipoint, Nonbroadcast Example
The following example illustrates a point-to-multipoint network with
nonbroadcast:

interface Serial0
ip address 10.0.1.1 255.255.255.0
ip ospf network point-to-multipoint non-broadcast
encapsulation frame-relay
no keepalive
frame-relay local-dlci 200
frame-relay map ip 10.0.1.3 202
frame-relay map ip 10.0.1.4 203
frame-relay map ip 10.0.1.5 204
no shut
!
router ospf 1
network 10.0.1.0 0.0.0.255 area 0
neighbor 10.0.1.3 cost 5
neighbor 10.0.1.4 cost 10
neighbor 10.0.1.5 cost 15
The following example is the configuration for the router on the other side:

interface Serial9/2
ip address 10.0.1.3 255.255.255.0
encapsulation frame-relay
ip ospf network point-to-multipoint non-broadcast
no ip mroute-cache
no keepalive
no fair-queue
frame-relay local-dlci 301
frame-relay map ip 10.0.1.1 300
no shut
!
router ospf 1
network 10.0.1.0 0.0.0.255 area 0
