Public bug reported: Our system has some statically defined network devices. Whenever a carrier loss happens, which can be due to manual network cabling changes but also due to the connected ISP's router doing a maintenance restart, the system receives a carrier loss. This results in all routes being removed. They are not added back when the carrier is regained.
I tried putting [Match] Name=* [Link] ActivationPolicy=always-up into /etc/systemd/network/netplan-override.network.d/override.conf , but this doesn't seem to help either. I don't see any way to specify that a carrier loss should be ignored via netplan. I suppose https://github.com/canonical/netplan/pull/34 introduced this for bridge devices. I'm actually surprised this isn't a bigger issue to people since.
