Hello everyone,
Having just configured systemd-networkd on my machine, I found myself no
longer assigned global IPv6 addresses. The LAN in question has got fully
operational native IPv6 support and both dhcpcd and connman had no
problems taking advantage of it. Networkd on the other hand picks up
router advertisements but ignores DHCPv6. Observed with systemd version
216 and 218. My network-configuration file is simply
[Match]
Name=en*
[Network]
DHCP=both
Enclosed you will find a debug log I have just obtained from
systemd-networkd, trimmed down to the IPv6 part. As you can see in it,
having received the RA networkd correctly identifies the local network
as managed and fires up the DHCPv6 client. The client then receives a
reply from the server and... does absolutely nothing with it.
Any idea what the problem might be? Thank you in advance - and of course
if you need any more information which might facilitate debugging the
issue, do let me know.
Yours sincerely,
