[Kea-users] DHCPv6 DUID-LL matching

[Marek Greško]

Hello,

I have working kea dhcpv6 setup. I am struggling with one problem. All my devices get correct IPv6 addresses from reservations by matching DUID. But one of the devices in the network have changing DUID, only the DUID-LL part is constant, so I tried to match on DUID-LL. I am convinced it was working before, but I cannot verify now. Nowadays I observe the device is getting the IPv6 address from pool. Not from the reservations.

My config contains:

"host-reservation-identifiers": ["duid", "hw-address"],

and the reservation itself:

{
"hostname": "host",
"hw-address": "01:02:03:04:05:06",
"ip-addresses": [ "fc00::7" ]
}

The addresses are example one, not the real. What could be the problem? I tried to delete the lease from the leases file and restart the kea, so it is not the lease before reservation problem, but the lease was again offered from the pool.

Thanks

Marek
