[Kea-users] Hosts Storage DB and multiple subnets/scopes

[mtint hpc]

Hi All,

We have pre-allocated all my desktops, 400+  in current DDI (replacing with
Kea/phpIPAM).
Hoping to do the same with kea. I see in section Hosts Storage,

// The example below is not optimal from a performance perspective, but it
// nicely showcases the host reservation capabilities. Please use the
minimum
// set of identifier types used in your network.



*  "host-reservation-identifiers":    [ "circuit-id", "hw-address", "duid",
"client-id" ],*

// Specify connection to the database holding host reservations. The type
// specifies that the MySQL database is used. user and password are the
// credentials used to connect to the database. host and name specify
// location of the host where the database instance is running, and the
// name of the database to use. The server processing a packet will first
// check if there are any reservations specified for this client in the
// reservations list, within the subnet (configuration file). If there are
// no reservations there, the server will try to retrieve reservations
// from this database.
  "hosts-database": {
    "type": "mysql",
    "reconnect-wait-time": 3000, // expressed in ms
    "max-reconnect-tries": 3,
    "name": "keatest",
    "user": "keatest",
    "password": "keatest",
    "host": "localhost",
    "port": 3306,
    "trust-anchor": "my-ca",
    "cert-file": "my-cert",
    "key-file": "my-key",
    "cipher-list": "AES"
  },

  "id": 1 <== is the subnet id?

how does it work with multiple subnets/scopes, is there a column to
identify a different subnet?
in *host-reservation-identifiers *

typically config but in my case reservations all in DB.
{
"subnet4": [
    {
        "id": 1,
        "pools": [ { "pool":  "192.0.2.1 - 192.0.2.200" } ],
        "subnet": "192.0.2.0/24",
        "interface": "eth0",
        "reservations": [
            {
                "hw-address": "1a:1b:1c:1d:1e:1f",
                "ip-address": "192.0.2.202"
            },
            {
                "duid": "0a:0b:0c:0d:0e:0f",
                "ip-address": "192.0.2.100",
                "hostname": "alice-laptop"
            },
            {
                "circuit-id": "'charter950'",
                "ip-address": "192.0.2.203"
            },
            {
                "client-id": "01:11:22:33:44:55:66",
                "ip-address": "192.0.2.204"
            }
        ]
    }
],

Michael
