It shouldn't matter if routed (-q) is running or not.  With a
private net (not connected to anything else), you don't need
to do anything - your IP & Netmask will tell the machine that
all the other machines are local.  If you run routed -q, nothing
will continue to happen as nobody's broadcasting RIP.

If you connect via a dial-up to the 'net, all you need to do is
set a "default" on the dialup machine to the other side of the
dialup, and a "default" on all other machines that points to the
dialup machine.  I suspect it's very rare that an ISP will broadcast
RIPs down a dialup.... there's no point - they'd just say "default
this way".  Therefore, having routed running doesn't matter.....
except for some reason, people report that routed keeps deleting their
default route.  This has *never* happened to me !!  The only reason
I can imagine is that routed is adding the route in the first place...
it's never been supposed to (and never has for me) delete static
routes (netstat -r has the 'S' flag).

Ppp is responsible for the line, and controls all routing table entries
for that line.  If ppp is to be used, there should be *absolutely
nothing* mentioned about tun* in /etc/sysconfig.  The *only* lines
that you need are

/etc/ppp/ppp.conf:
    ifaddr 10.10.10.10/0 10.10.10.11/0 255.255.255.0
    delete ALL
    add 0 0 HISADDR

/etc/ppp/ppp.linkup:
    delete ALL
    add 0 0 HISADDR

Hope this helps.
