[Kea-users] Lease affinity of released leases

[Peter Davies]

Hi Johannes,

 One of Kea's built-in classes is the "DROP" class. Packets associated with this class are, as the name suggests, dropped.

You can test for dhcpv4 DHCPRELEASE packets with "test": "pkt4.msgtype == 7"

Which gives the following:

   "client-classes": [

       {

           "name": "DROP",

           "test": "pkt4.msgtype == 7"

       }

   ]

   or for dhcpv6

  "client-classes": [

       {

           "name": "DROP",

           "test": "pkt6.msgtype == 8”

       }

   ]

 /Peter

Hi Johannes,
   If you don't want to define host reservations you can give the client very long lease times and get Kea to drop   DHCPRELEASE packet

Hi Peter, Thanks for your reply!

Do you know of an easy way to drop the DHCP Release package with KEA using only configuration, or would it require writing a hooks library as was suggested in another reply? I can't find anything in the docs about such a feature.
