It is not the case. As I mentioned earlier, the interface metric is used to select the best interface. However, both are always up. Incidentally, this results in a benefit of Linux over Windows. On my notebook computer, I have different IP addresses for Ethernet & WiFi interfaces. When I connect with Ethernet and WiFi is connected, I can reach my WiFi address from my home network, as well as the Ethernet address. This means no matter how I'm connected I can connect to the notebook with the same IP address/host name. However Wireshark shows the traffic going through the Ethernet port, even when the WiFi address is used. This does not work with Windows. Then I have to specify a different address, depending on whether I have an Ethernet connection.
In this same laptop, when running 42.3, and using the same IP for both interfaces, I get "martians" and failures. I have to manually disable one (the wifi). I don't know the metrics in that case, I'll find out.
I never said use the same IP address for both interfaces. Only that Linux allows you to reach the WiFi address, even when connected via Ethernet.
But I do want both interfaces to have the same IP, and have only one active at a time. I want to do on another computer "ssh laptop" and be sure to reach it no matter if it is on WiFi or cable. I do not want to do "ssh laptop_eth" or "ssh laptop_wifi" depending.
When running Leap 15.0, different IP for each, different metrics, but same network - they connect to the same exact router, they are in the same segment - things work, except traceroute.
Make sure your firewall is turned off.
But I do want it on. Anyway, I disabled the firewall on the laptop and still traceroute fails. It is the firewall (SuSEfirewall, Leap 42.3) at the destination that is the culprit. -- Cheers/Saludos Carlos E. R.
