[Kea-users] reservations issue

[Darren Ankney]

Hi,

I'm not sure what version you are running, but in the latest stable
(2.6.1), "reservations-global" defaults to false so Kea would not find
these reservations.  You can either set this flag to true or you can
move the reservations for the IP addresses into their respective
subnets (better solution).

See: https://kea.readthedocs.io/en/kea-2.6.1/arm/dhcp4-srv.html#fine-tuning-dhcpv4-host-reservation
