Title:
systemd-network installs adjacency routes to DNS servers from DHCP
even if they're off-net
Status in systemd package in Ubuntu:
Confirmed
Bug description:
This is a known issue upstream:
https://github.com/systemd/systemd/issues/28495
and indeed a fix is milestoned for v255:
https://github.com/systemd/systemd/pull/28508
It would be good to see this in the next backports build.
Note: this bug only manifests when the DHCP server is sending you a
list of DNS servers (fairly common) as well as static-classless-routes
(option 121... much less common).
