Inverse ARP is enabled by default and it maps the network addresses to the
DLCIs for directly connected devices only. What i mean is that if you have a
hub and spoke topology then inverse arp will allow the spokes to see the hub
address and the hub to see both the spoke addresses but it will not allow
the spokes to see eachother because they do not have a pvc between them.
Regarding what you mentioned about inv arp running only on point to point
links, well i think this is wrong. There is no need to run inv arp on point
to point links and it does not run on them. It is used when you have a
multipoint subinterface or when you are using the physical interface but it
can be turned off using the no inverse-arp command.
About your lab; well what do you see when you issue the command show
frame-relay map ?
