setting routes

Hi list!

I want to modify the routing table, but got into trouble.
I have two machines on different subnets, but they are on the same hub.
So I want to tell the kernel that the other machine does not need to go
through the default gateway, but can directly access it. In Linux I do it
like this:

route add otherhost eth0

this tells the kernel that otherhost can be directly reached on the eth0
interface. Doing this in NetBSD does not work:

route add otherhost ie0
=> route: bad value: ie0

What can I do?

Cheers,
Henning
