Hi,
: I've had the same problem. I sorta wish there was an "ip rule flush" : command that would leave only the default rules.
Would be nice.
I have a function called "flush" which flushes all tables and all rules other than the main routing table. Here's the "rule" flush portion. It won't win any points for elegance, but it should get the job done:
ip rule show | grep -Ev '^(0|32766|32767):' \ | while read PRIO RULE; do ip rule del prio ${PRIO%%:*} $( echo $RULE | sed 's|all|0/0|' ) done
This is what I've used in my iproute2 shell library package, maybe it's a bit more elegant (only one fork involved). Since we change our local, main and default table in our distro to different values I've added a KEEP variable. Prepend it to adjust to your settings.
: ${KEEP:="local main default"}
while read prio rule; do
continue=0
for keep in ${KEEP}; do
if [ "${rule//lookup ${keep}/}" != "${rule}" ]; then
continue=1
fi
done
if [ ${continue} -eq 0 ]; then
ip rule del prio ${prio%%:*} ${rule//all/0/0}
fi
done < <(ip rule show)Best regards,
Roberto Nibali, ratz
