Have you checked to see if you have a dynamic frame-relay mapping
between the two spokes? It looks like R4 has a frame-relay mapping to
R3. This could happen if you disabled inverse-arp after the interface
was up/up with an IP address applied.

Subject: OSPF/FR: why spoke-spoke relationships try to form?
Problem: 3-router hub-spoke FR/OSPF network using physical interfaces,
frame
map statements, ip ospf point-to-multipoint. There is a "live" but
unused
PVC between the two spokes. Why do spokes constantly try to create an
OSPF
neighbor relationship over "unused" PVC & how to prevent other than by
shutting down the unused PVC between them? It doesn't seem right for
this
waste of CPU and bandwidth to be occurring. Thanks.
