Hi,
We have a strange issue using Kea-DHCP 1.8.2 where sometimes the wrong IPv6
subnet is sometimes selected, even when there is a matching relay address.
This usually happens when de device goes offline, and comes back, when we
restart the kea-dhcp6 server, the correct subnet is selected again and
device comes online.
Can somebody clarify /help with this rather strange behavior?
I've also opened an issue regarding this behavior.
