[Kea-users] Subnet only for host reservation

[egor.grijuc at orange.com]

Hello.
I am trying to setup configuration where entire subnet must be used with host reservation in database.
Configuration is following:
Client class with condition that should never exists:
curl -X POST -H "Content-Type: application/json" -d '{ "command": "remote-class4-set","arguments": {"client-classes": [{"name": "DenyAll","test": "option[60].hex == 0x53686f756c644e65766572457869737473"}],"remote": {"type": "mysql"},"server-tags": [ "all" ]}, "service": [ "dhcp4" ] }'

53686f756c644e65766572457869737473 = "ShouldNeverExists"

Shared network with matching to client class "DenyAll".
Client class mathing is on shared network level.
Than I defined subnets in this shared network
And host reservation with circuid id option also in database.

curl -X POST -H "Content-Type: application/json" -d '{ "command": "reservation-add","arguments": {"reservation": {"subnet-id": 1,"circuit-id": "0x43484e3131","ip-address": "89.149.76.55"}}, "service": [ "dhcp4" ] }' http://192.168.80.69:8000/

The problem is that with this scenario I get "DHCP4_SUBNET_SELECTION_FAILED" message in the logs.
But if I remove client-class option from shared network device gets ip address that I defined in host reservation.
Is there a way to setup kea to allocate leases from pools from shared networks only with host-reservation?
