the route-<if> and rule-<if> are invoked by ifup-routes (all this in
/etc/sysconfig/networking-scripts), and it appears they are read and
each line is appeneded to
/sbin/ip rule add $line
or
/sbin/ip route add $line
respectively.
now, it also appears the routes are processed before the rules, not
sure, but this could be a complication?
actually, upon further perusal, the ROUTES section is parsed as...
if [ -f "$file" ]; then
if egrep -q '^[[:space:]]*ADDRESS[0-9]+=' $file ; then
# new format
handle_file $file ${1%:*}
else
# older format
{ cat "$file" ; echo ; } | while read line; do
if [[ ! "$line" =~ '^[[:space:]]*(\#.*)?$' ]]; then
/sbin/ip route add $line
fi
done
fi
where 'older format' is as I described, I'm not quite sure what that
egrep is looking for, but it appears the new format its looking for is...
ADDRESSn=<network>
NETMASKn=<prefix>
GATEWAYn=<next-hop>
(for n=0,1,2,...)
and it constructs a
/sbin/ip route add <network>/<prefix> via <next-hop> dev <if>
from each triplet of these...
AH, yes, here, this shows it... http://kbase.redhat.com/faq/docs/DOC-8024
now, this makes no provisions for routes that have rule table #s.
apparently the rules-<if> files were added to rhel5 and finding /any/
documentation is challenging.
