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

[Diogo André de Assumpção]

Thanks for the reply!

So, In ISC DHCP, would that config mean that the `dhcp6. bootfile-url` option following the vendor-class would only be sent to clients matching that class?

Thanks,

Hi Diogo I ran this config snippet through Keama and got: Started parsing new subnet declaration in line 1 (. . . )/bc97e1f6-17a1-11f0-8122-0242ac120002. conf line 3: unknown option dhcp6. vendor-class option dhcp6. vendor-class 0 ^ Could this be

Hi Diogo
   I ran this  config snippet through Keama and got:

Started parsing new subnet declaration in line 1

(...)/bc97e1f6-17a1-11f0-8122-0242ac120002.conf line 3: unknown option dhcp6.vendor-class

  option dhcp6.vendor-class 0

               ^

Could this be because option 16 is expected to be sent by the client and not by the server?

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<https://urldefense.com/v3/__http:/deploy.cisco.com/install/ipxe2/ipxeb.efi__;!!Bt8RZUm9aw!_7Pw9jyv9RtUR1CuvwITq7M3xO6uqAO0upBEpcJiKGVOtN8k29ar6kSCssKgXnr_QDO6PA$>";
  pool6
  {
      range6 2001:DB8:1234::320 2001:DB8:1234::1000;
  }
}


Kea
