default gateway on different subnet

[Petar Bogdanovic <petar%smokva.net@localhost>]

Hello,

what is the proper NetBSD equivalent for the following two linux
route-commands in a situation where one host has not just one network
interface but also the problem that the default gateway is not on his
subnet:


   ifconfig eth0 200.2.116.140 netmask 255.255.255.0

   route add -net 200.2.117.0 netmask 255.255.255.240 dev eth0
   route add default gw 200.2.117.1


My first guess was the following (vr0 = eth0):


   ifconfig vr0 inet 200.2.116.140 netmask 255.255.255.0

   route add -net 200.2.117.0 -netmask 255.255.255.240 -link vr0 -iface
   route add default 200.2.117.1


but it didn't work. Unfortunately I also can't tell why exactly because
the machine is located in a datacenter far away from here and I have to
rely on a few notes made by busy technicians. What I do know is that the
NetBSD-image always boots up successfully (according to eyewitness
account ;).


After digging through the archives I also found this, but it didn't work
either:


   ifconfig vr0 inet 200.2.116.140 netmask 255.255.255.0

   route add -host 200.2.117.1 -link vr0 -iface
   route add default -ifa 200.2.116.140 200.2.117.1

   (http://mail-index.netbsd.org/netbsd-help/2006/12/15/0000.html)


I tried to reproduce the scenario on a similar qemu-setup and found out
that adding the other subnet fails with `Network unreachable' while
adding a host works as expected (at least that's what `route show' told
me).


Any help is greatly appreciated,

Petar


P.S. That's how the linux routing table looks like, when the Debian
     rescue-image is loaded:

     # route -n
