[Kea-users] valid-lifetime is short than preferred lifetime

[Veronique Lefebure]

Hi,

Our client is refusing an ipv6 lease offered by KEA:

 
[root at cs-lab11-kea ~]# dhclient -6 -v enp7s0f1

Any idea why KEA returns 7500 as Max lifetime ?
It is not configured like that.
We have:

"valid-lifetime": 86400,
"min-valid-lifetime": 86400,
"max-valid-lifetime": 86400,
"preferred-lifetime": 86400,
"renew-timer": 32400,
"rebind-timer": 48600,

Thanks
