[Kea-users] ISC DHCP to Kea – Why KeaMa comments some options?

Hi all,

I’m using KeaMa to validate a few things around a planned migration from ISC to Kea. I noticed that for some v6 options the script will output a Kea version of the ISC config, but comment it out. Any idea why?

Here’s an example:

ISC:

subnet6 2001:db8:1234::/64 {
  option dhcp6.name-servers 2001:DB8:1234::53;
  option dhcp6.vendor-class 0 10 "HTTPClient";
  option dhcp6.bootfile-url "http://deploy.cisco.com/install/ipxe2/ipxeb.efi";
  pool6
  {
      range6 2001:DB8:1234::320 2001:DB8:1234::1000;
  }
}


Kea

  "id": 1997,
  "subnet": "2001:db8:1234::/64",
  "option-data": [
    {
      "space": "dhcp6",
      "name": "dns-servers",
      "code": 23,
//          "original-data": "2001:DB8:1234::53",
      "data": "2001:db8:1234::::53"
    }
//        {
//          "space": "dhcp6",
//          "name": "vendor-class",
//          "code": 16,
//          "data": "0, 10, HTTPClient"
//        }
//        {
//          "space": "dhcp6",
//          "name": "bootfile-url",
//          "code": 59,
//          "data": "http://deploy.cisco.com/install/ipxe2/ipxeb.efi"
//        }
  ],
  "pools": [
    {
      "pool": "2001:db8:1234::320 - 2001:db8:1234::1000"
    }
  ]
},


Thanks!
