kea-hook-dynamic-lifetime

Kea dhcp hook for setting lifetime by IP address and MAC address

Usage

example config:

    "hooks-libraries": [
        {
            "library": "/usr/local/lib/kea/hooks/libdynamic_lifetime.so",
            "parameters": {
                "options": [
                    {
                        "mac-address": "00:11:22:33:44:55",
                        "valid-lifetime": 3600
                    }, {
                        "mac-address": "00:11:22",
                        "valid-lifetime": 7200
                    }, {
                        "ip-address": "192.168.10.0/24",
                        "valid-lifetime": 72000
                   }
                ]
            }
        }
    ],

This config is

• Set lifetime to 3600 if MAC address is 00:11:22:33:44:55
• Set lifetime to 7200 if MAC address starts with 00:11:22
• Set lifetime to 72000 if leased IP address is in 192.168.10.0/24
• Otherwise, default lifetime is used.

The higher the setting, the higher the priority. The IP address parameter must be CIDR form.

These config override other valid-lifetime config (ex. global config, subnet config).
