Frame Relay InArp Question

Dear Friends,

If ive configured say R1's sub-interface as "multipoint" while R2's
sub-interface as "point-to-point", and I dont configure static FR to IP
mapping on the multipoint interface of R1, will the R2's sub-interface reply
to R1's InArp request? What ive understood so far after running debugs is
that R1 sends an InArp request to find out about DLCI-to-IP mapping and R2
replies to the request. But wherever i check i find that InArp is disabled
when we configure the sub-interface as "point-to-point", if thats the case
than how am I seeing dynamic FR mapping on R1?
