Subnetting

Set up the scenario a little here:

We have a /23 network coming in through a Cisco router. At the moment, our
Linux box is using proxy arp and has the network divided into two pieces. I
want to elimate proxy arp and use the Linux box as a proper router.
Basically I want to take our /23 and cut it into two /24s.

I'm pretty sure I can do the configuration on the Linux box, but the Cisco
box has me a little confused. I think it might be as simple as the IOS
command:

ip route y.y.y.y 255.255.255.0 x.x.x.21

(where y is the upper /24 and x is the lower /24).

Does anybody have any experience in this?
