Persist ip route and ip rule configurations for Policy Based Routing (iproute2)
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 inroute-(device)will generate aip route add (contents of line here)and every line inrule-(device)will generate aip rule add (contents of line here), but it's possible that NetworkManager has different ideas.

Sadly the route-(device) file seems to completely ignore the table parameter. :(

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...
