In a multipoint interface, you need something to map L3 to L2 reachability.
In ethernet, we have ARP to do that for us.  In frame-relay, we have either
Inverse-ARP (on by default, but likely disabled in the lab) or we have
static mapping.  
 
But this MUST be done, or we have no reachability and therefore can't
encapsulate!
 
Cheers,

 I have just executed Debug IP Packet, and in fact seem like that knows the
interface to use, however the message Encapsulation failed revealed no
information L2-L3, I thought to reach directly connected although without
static mapping. In the meantime I thank you everyone for support.

Try looking at the output of "debug ip packet" as you do the various pings!
That may help highlight the missing piece there from pinging yourself versus
the other devices!

I`ve just configured Frame-Relay Hub and Spoke, plus point-to-point.
with point-to-point no problem, with Hub and spoke I pinged only the spokes
but not myself,same thing for both spokes, not reachability for myself.
Can someone help me?
Straight forward the config for Hub:
