Adding routes to another table: no such process

Hi,

I'm having a hard time setting some routes on a router and can't find any
relevant information anywhere, so I resort to asking on this list.

The router has one interface, say eth0, with configured address 10.0.0.1/32.

Now I would like to do:

  ip rule add from 10.0.0.1 table 100
  ip route add 10.0.0.2/32 dev eth0 table 100
  ip route add 10.0.0.3/32 via 10.0.0.2 table 100

but I get

  RTNETLINK answers: No such process

on the third command.  It's just as though the kernel refused to use a
gateway for which there's no route in the main table.  Is this an actual
requirement for gateways?  I could find some examples around the web setting
routes with gateways in other tables than main, but they obviously don't work,
yielding the same error message.

Thanks for your help.
