[Techtalk] arp

[coldfire]

playing with arp i am ... question:

here's the scenerio (completely hypothetical) .. the network id is 10.0.0
... the router, hostname router, has a host id of 5.  now a machine, 
hostname bob, is separated from the 10.0.0 ethernet by the router with a
host id of 10. in order to get the router to act as a proxy arp for that
host, i believe the correct syntax would be:

arp -v -i eth0 -s 10.0.0.10 0:0:0:0:0:1 pub

where 0:0:0:0:0:1 is the mac address of the router.

then in the arp cache, is the following:

? (10.0.0.10) at * PERM PUP on eth0

now when i ping 10.0.0.10 from some host, we'll say 10.0.0.100, shouldn't
the router send an arp reply for the 10.0.0.10 ip with it's own mac
address?  and thus be in the arp cache on the 10.0.0.100 machine?

if so, i've screwed something up .. if not, anyone wanna point out what
i'm missing?  thanks
