Currently running on Fedora Server 23, I've been searching for the right way to persist commands such as:

ip route add default via 10.0.2.1 dev ens32 table EXAMPLE_TABLE
ip rule add from 10.1.2.50 lookup EXAMPLE_TABLE prio 1000

either through nmcli (ideally) or through some other, similarly, sane way.

I've seen examples like lodging it on the route-ifname file but that don't seem to execute the default rule correctly.

If you run ip route show table EXAMPLE_TABLE after a reboot you'll realize it doesn't stick - at least in my experience.

Any insights into this would be lovely, thank you.

  • My recollection is that every line in route-(device) will generate a ip route add (contents of line here) and every line in rule-(device) will generate a ip rule add (contents of line here), but it's possible that NetworkManager has different ideas. – Ulrich Schwarz Dec 7 '15 at 20:36
  • Sadly the route-(device) file seems to completely ignore the table parameter. :( – Canha Dec 7 '15 at 21:14

The easiest way I know of to persist the default route is to add the default route destination to the /etc/sysconfig/network-scripts/ifcfg-<device> file as the value for GATEWAY. This creates that default route every time that interface is brought up, the other routes are persisted through the route-<device> files in the same directory.

  • Unfortunately this doesn't work if you are using policy based routing... – Canha Dec 7 '15 at 22:33
