Ah, looking closer I think I may have found why the bootfile-url was also
commented.
Somewhere else in the ISC DHCP config file we have:
```
option dhcp6.bootfile-url code 59 = string;
```
Which keama converts to this:
```
// /// Kea does not allow redefinition of options
// {
// "space": "dhcp6",
// "name": "bootfile-url",
// "code": 59,
// "type": "string"
// },
```
And after that all occurrences of the bootfile-url option are commented out.
Sorry that I missed this initially. Thanks for the support!

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, – Diogo From: Kea-users <kea-users-bounces@ lists.

Hi Diogo I ran this config snippet through Keama and got: Started parsing new
subnet declaration in line 1 (. . . )/bc97e1f6-17a1-11f0-8122-0242ac120002.

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
