the "no frame-relay inverse-arp" command disable inverse-arp between the
spokes only.
I don't see a need to configue subinterfaces in the hub as long as all the
routers are in the same subnet.
With such config I'd expect to see on the hub, R1 2 dynamic entries for the
DLCI's of R4 and R5 pointing out S0/0
The configuration is correct if R1 is the hub and wants learn about R4 and
R5's maps dynamically.
