*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))
