Yes, as it it seems, there is an issue with infinite lease time (4294967295
is UINT_MAX) :-/

This is a different issue, please open a new report about.

Either the router IPv6-RA��� or the local config says, wicked should use
 DHCLIENT6_MODE=managed
to acquire an IPv6 address, but the dhcp6 server isn't acting in managed
but in info-only mode and delivers a lease without any IP; wickedd-dhcp6
has to discard / ignore such responses by RFC.

Please install the "radvd" package and let "radvdump" running for a while
to see the RA that arrives on the interface(s) or capture dhcp6 and icmp6
(contains router RS/RA) packets, using tcpdump:
 tcpdump -w dhcp6.pcap -s 65535 -Uvnfi any 'icmp6 or port 546 or port 547'
while `wicked ifup all` (=rcnetwork start) is running.


In both cases, please provide logs as described at:
