Are you just doing default routing, or do you need RIP support?
ROUTED(8) offers RIP support, but you seem to be in need of the former,
which you can do with IPF or Zebra (see pkgsrc).  Check the website & man
pages for details and examples (ingore the IPNAT stuff)

I hate to say it, but the cisco is probably a "safer" solution, but that
might be a prelude to a debate thread which I dont' wish to start, I'm
just speaking from a network security standpoint.
