ARP is still required on ethernet links, so that the MAC address can
be
discovered for use in the ethernet frame header. /31 does not change the behavior of ARP at all. -- Nathan Ward
I often manually configure the MAC addresses in static fashion on point-to-points to eliminate the ARPing but that is nothing unique to a /31. It does eliminate the need for ARP, though.
