[Kea-users] Client class in host reservation

[Tomek Mrugalski]

Hi Maria,

Hope you're doing well. Apologies for not responding earlier. We looked
at the issue and it seems the code treated the client classes
differently for options and fixed fields, such as boot-file-name. This
problem manifested itself if a packet belonged to two classes and you
had the values defined in both. Anyway, this has been fixed now and
released in 1.9.5. Would you be willing to check if this updated
behavior address your needs? Also, if you're interested, the
improvements were done in ticket #1672. You can see the details here:
https://gitlab.isc.org/isc-projects/kea/-/issues/1672

If it doesn't, can you open a new ticket for this?

Hope that helps,

Tomek
