And it shouldn't, you haven't given it an appropriate route. From route(8):
The other commands have the following syntax:
route [-n] command [-net | -host] destination gateway
where destination is the destination host or network, gateway is the
next-hop intermediary via which packets should be routed.
There's the important part right there: gateway is the *next-hop* intermediary
via which packets should be routed.
