Hi!

I have an interface configured with two IP networks, let's say 10.1.0.0
and 10.2.0.0, like:

exp1:
flags=8963<UP,BROADCAST,NOTRAILERS,RUNNING,PROMISC,SIMPLEX,MULTICAST>
        link type ether 0:50:8b:df:bf:e2 mtu 1500 speed 100Mbps
        media 100baseTX full_duplex status active
        inet 10.1.0.1 netmask 255.255.0.0 broadcast 10.1.255.255
        inet 10.2.0.1 netmask 255.255.0.0 broadcast 10.2.255.255


If I get an arp-request like:

ARP: Who has 10.1.0.1? Tell 10.2.0.x

i.e an arp-request crossing network boundary.

How should a proper arp behave? Should the request be ignored?
