--- Begin Message ---Package: systemd Version: 246.4-1~bpo10+1 Severity: important Tags: ipv6 Dear Maintainer, The current BPO release of systemd includes a serious regression; valid SLAAC v6 addresses and routes are discarded under certain circumstances. I believe this to be an instance of https://github.com/systemd/systemd/issues/16719 which is possibly fixed by https://github.com/systemd/systemd/pull/16725 The user-visible symptom is that the systems stop responding on their SLAAC-configured v6 addresses until the link is next reconfigured; some time later they drop these addresses again. An extract from the debug log from systemd-networkd follows: note in particular the "Removing address" and "Forgetting address" lines in the log. I think that pull/16725 should be cherry-picked into Debian as soon as possible.
