[Kea-users] option 43 coming back blank

[Victoria Risk]

Hi Alan,

A couple of weeks ago we had a webinar on configuring custom vendor options in Kea. You might find it to be helpful.
The slides are here: https://www.isc.org/docs/2023kea_custom_options.pdf and the recording is here: https://www.youtube.com/watch?v=mcXO7E9K190&feature=youtu.be

Regards,

Vicky Risk
