You won't be able to ping your own IP address on multipoint framerelay interface. For the ping to be successful, ICMP echo packets must be sent and ICMP echo replies must be received. On a point-to-point subinterface, the router on the other side of the link sends ICMP echo replies and the ping succeeds. Whereas, on a multipoint subinterface, there is no remote ip-dlci mapping for every destination. Lack of mapping on a multipoint subinterface prevents the router from sending the echo packet out to the other side. The router does not have any layer-two to layer-three mapping for its own address either and does not know how to encapsulate the packet and the ping fails. Hope that helps!
