FreeBSD runs by default ``routed -q'' only, and you are being asked in
the post-installation configuration menu whether you do want this.  (I
generally turn it off since i've got a real router setup, with one
machine collecting and approving all RIP requests, and properly
managing the routes.)

Even routed -q is considered a mistake by some (many?) people, but it
does less harm in that it never sends RIP annoucements.  It is only
that this ``used to be so all the time'', since people got used to
this lazy routing table management.

The router discovery protocol (rdisc) is supposed to be better, but i
don't have any experience with it.

If you need to _supply_ RIP information (who is listening to it?), you
are strongly suggested to run GateD, since it allows a much better
control of what is being sent, and what is being accepted.  routed
believes everything, and (if i'm not mistaken) basically announces
everything if requested to do so.

If things already work without routed, nothing.  If you need some sort
of routing advertisement, you get better control about the RIP
annoucements (or even non-RIP protocols at all).
