<br>
Have a look here:<br>
<a href="https://kea.readthedocs.io/en/kea-2.2.0/arm/dhcp4-srv.html?highlight=%22vendor-encapsulated-options%22#dhcpv4-vendor-specific-options" rel="noreferrer" target="_blank">https://kea.readthedocs.io/en/kea-2.2.0/arm/dhcp4-srv.html?highlight=%22vendor-encapsulated-options%22#dhcpv4-vendor-specific-options</a><br>
<br>
You might need to setup encapsulated sub-options and tell Kea to<br>
include the "vendor-encapsulated-options-space" content in the options<br>
as a sub-option:<br>
<br>
"option-data": [<br>
{<br>
"name": "REPLACE_ME",<br>
"space": "vendor-encapsulated-options",<br>
"code": 1,<br>
"csv-format": false,<br>
"data": "74657374"<br>
},<br>
{<br>
"name": "vendor-encapsulated-options"<br>
}<br>
]<br>
<br>
So, above, first the data is added as a sub-option of option 43<br>
(option 43 typically consists of one or more sub-options). Replace<br>
"REPLACE_ME" with the name of the sub-option you are trying to send (I<br>
think you can omit name entirely if there is none as that part isn't<br>
sent). Set the code to the correct sub-option number. If this<br>
particular data should not be a sub-option, then you might have to do<br>
something like this:<br>
<br>
{<br>
"code": "43",<br>
"csv-format": true,<br>
"data": "74657374",<br>
},<br>
<br>
please note that if "csv-format" is set to false, then Kea will be<br>
expecting "a hexadecimal string." see:<br>

<br>
Can you share the option 43 portion of the ISC DHCP configuration you<br>
are trying to convert if you still have trouble?<br>
<br>
Thank you,<br>
