*via* the interface *to* the gateway
interface vlan417
ip addr 10.0.0.2 255.255.255.252
ip route 192.0.2.0 255.255.255.0 vlan417 10.0.0.1
never ever point a route to a broadcast interface unless you *want* it
to generate ARP traffic for every IP address in there.
(Including the interface in a route when there is a gateway set is good
practice, though, as the route will go away if vlan417 goes to "down",
instead of dangling around and causing mishap)
((ObRant: Proxy-ARP on-by-default is one of the most stupid moves Cisco
ever made, nearly as bad as the 6500/7600 BU split))
