The metric is 1024, while for instance network-manager assigns these numbers: ethernet -> 100 wlan -> 600 wwan -> 700 This happens because ethernet devices are managed by default by networkd in ubuntu-core, while wlan and wwan are managed by network-manager if installed. It would make sense to either assign a metric of 100 in networkd configuration file or change network-manager snap so it handles ethernet in all cases when installed. - SRU TEST CASE: - * Set up an ethernet and wifi connection using netplan, and check metrics in "ip route". With the current version they have "1024", with the proposed update the ethernet one will have 100, the wifi one 600. + [Test Case] + * Set up an ethernet and wifi connection using netplan, and check metrics in "ip route".
