Hi,
I don't fully agree that option 150 can be anything. It is a standard
DHCP option defined in https://www.rfc-editor.org/rfc/rfc5859.html and,
as Veronique said, it's also recognized by ISC DHCP
(https://kb.isc.org/v1/docs/isc-dhcp-44-manual-pages-dhcp-options#standard-dhcpv4-options).
That's why we would expect it to be recognized by Kea as well without
the need to define it ourselves (as we do now).
Cheers,
Maria

Hello,
In ISC DHCP v4.4.2 we have
(https://downloads.isc.org/isc/dhcp/4.4.2/dhcp-4.4.2-RELNOTES
<https://eur03.safelinks.protection.outlook.com/?url=https%3A%2F%2Fdownloads.isc.org%2Fisc%2Fdhcp%2F4.4.2%2Fdhcp-4.4.2-RELNOTES&data=04%7C01%7Cgr306%40universityofcambridgecloud.onmicrosoft.com%7C3bf0cfae0b6e4bed9d9008d9d4e3efb1%7C49a50445bdfa4b79ade3547b4f3986e9%7C0%7C0%7C637774899185495933%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C2000&sdata=vlNzPfz5%2B0C0vFxsPpCtcNTWNv9SMiiEoEPUqD0KmKM%3D&reserved=0>)
:
Support for sending and receiving additional DHCP4 options has been
added to both the dhcpd and dhclient. Specifically: option codes
93,94, and 97 (RFC 4578); code 150 (RFC 5859); and codes 209,219, and
211 (RFC 5071). Beyond configuring, sending, requesting, and receiving
these options neither server nor client apply any additional logic
based on their values. Thanks to Peter Lewis for requesting this
change. [ISC-Bugs 47062]
In KEA, it seems that option 150 is not support.
We get this error:
[Validation] Error encountered: definition for the option
'dhcp4.tftp-server-ip' having code '0' does not exist
Is there a solution or do we have to define that option ourselves?
Thanks,
Veronique
