I solved this problem with below configuration. But it is work on KEA 1.1.0,
it does not work on KEA 1.3.0. When I restart service on KEA 1.3.0, I see
failed log "unexpected keyword "client-class" in pools map". When I gave
wrong information in client-classes (example; true circuit-id:0x012E0105 but
I gave false circuid-id:0x00070108), it still gets IP. So it does not care
about evaluation. Why?

  "client-classes": [

   {"name": "opt82", "test": "substring(relay4[1].hex,2,4) == 0x012E0105 and
substring(relay4[2].hex,2,6) == 0x44656e656d65"}],

 

  "subnet4": [

    {

       "subnet": "10.0.100.0/24",

       "pools": [

       {

        "client-class": "opt82",

        "pool": "10.0.100.220 - 10.0.100.220"

       }

      ]

   }

]

.

.

 

Except that, I want to add a new client-class but when I add the new
client-class, it does not evaluate as I want. Same situation as above. If
first discover comes from second client, kea giving first IP (10.0.100.220)
although client-class (opt82try) is not match. In this case, I am writing
client-classes for nothing.

   {"name": "opt82try", "test": "substring(relay4[1].hex,2,4) == 0x012E0105

       {

        "client-class": "opt82try",

        "pool": "10.0.100.221 - 10.0.100.221"
