Bug Description
Hello,
It happened now twice for me that after a "unattended update" the linux kernel is missing routes which were announced via BGP. From my point of view, the problem is that networkd is restarted(?). Which leads to a deletion of the routes in linux kernel.

As you can see 10.3.0.0/16 and 10.4.0.0/16 is missing in "ip route"
Hi,
Thanks for taking the time to file this bug and trying to make Ubuntu better.
This systemd-networkd behavior has been seeing in other bugs, like:
