dhclient doesn't set that route.  The kernel's networking code
automatically creates a route for the subnet when you add the IP to
the interface.

You can check this like so:
  ifconfig re0 172.20.0.1/24
  netstat -rn

Replace re0 with your interface.  You'll notice that just by adding an
IP with a subnet mask to an interface, you get a route for that subnet
created.
