Bug#905503: networkd doesn't like fritzbox' IPv6 announcement, interface degraded

Sun Sep 30 09:46:34 BST 2018

I'm not sure if I have the exact same problem. I also have a Fritzbox.
At boot (or systemctl restart systemd-networkd) my machine running
stretch is able to obtain an IPv6 global address and networkctl
reports no problem. After several days the IPv6 global address
disappears, leaving only a link-local address. This problem
disappeared - tested for several months - after cherry-picking
[6554550f]. See also [GH#3879].

Best, Joost
