Re: [SOLVEd] reload /etc/iproute2/rt_tables

First to find out table names
# ip route show table all | sed -n "s;.*table\s\(.*\)\sproto.*;\1;p"
...
local
...
Then print by name
# ip route show table local

Tables are not created by default.

# ip r show table 17
Error: ipv4: FIB table does not exist.
# ip r add to 1.2.3.4 via 192.168.1.1 table 17
# ip r show table 17
1.2.3.4 via 192.168.1.1 dev wlan0 
# ip r del to 1.2.3.4 via 192.168.1.1 table 17
# ip r show table 17
#

Notice there was no error after last ip show command, as table now exists

Also you do not need to reboot to reload /etc/iproute2/rt_tables

New settings apply immediately.

I use systemd-networkd.

man systemd.network
[ROUTE] and [ROUTINGPOLICYRULE] sections
