Also it is strange, that IP address assigned to eth0:0 in config file is used by eth0. /var/log/messages shows nothing about network configuration errors on either eth0 or eth0:0. system-config-network seem to understand all settings correctly and resaves them ok also. "ifup eth0:0" executes ok, but ifconfig afterwards shows no eth0:0 device ...
15.10.2021 · $ sudo ip addr add 192.168.1.100/24 brd + dev eth0 label eth0:0 Don’t forget to put the interface up, or it probably won’t be very useful. $ sudo ip link set dev eth0 up You should now be able to use your virtual network interface for whatever you want. You can see the full configuration by viewing the output of the ip a command.
It seems that eth0:0 gets to be the one each time, so by hardcoding GATEWAYDEV="eth0" you make sure that eth0 is always selected as the gateway device. In older versions of RH you could just edit /etc/sysconfig/static-routes and add default via 5.x.y.82 dev eth0 As a last resort /etc/rc.local is always your friend! Share Improve this answer

It examines the route to the gateway IP with ip get route to GATEWAY and, using sed, matches the a device. It seems that eth0:0 gets to be the one each time, so ...
