Wrong, it is evaluated when this line is executed:
                    eval route_args=\$route_${i}

I wrote this code 4 years ago, it works, has been working and
will continue to work.  Please, just leave the static/default route
stuff alone.

No, the comment is correct as it stands, set it to ``NO'' or set
it to the IP address of the defaultroute + any funky route flags
you may want on it.

Boo bad, your value of route_default will be smashed by rc.network
when it does ``route_default="default ${defaultrouter}"''.  You'll
end up with the command ``route add default YES'' being executed,
not something you really want :-)

NO!  Do not agree, read and understand what the trick above is,
``eval route_args=\${route_${i}'' when $i="default'' grabs the
route_default for you.
