Hi,
I'm using isc-kea-dhcp6 (2.4.1-isc20231123184533) on Debian bookworm and am
having a minor logging issue. I've got a minimal config that defines a single
subnet, an allocatable pool within that subnet and a single reservation.
The host gets its reserved IP successfully, but there's always a WARN log dance
in the kea logs with ALLOC_ENGINE_V6_ALLOC_FAIL_SUBNET,
ALLOC_ENGINE_V6_ALLOC_FAIL_NO_POOLS and ALLOC_ENGINE_V6_ALLOC_FAIL_CLASSES.
Are these warnings expected, or have I misunderstood something about the
configuration?
Thanks,
Andrew
