[Kea-users] ISC DHCP equivalent of the "group" statement

[Kamil Wilczek]

Dear All,

for more than a decade we successfully used ISC DHCP (hunderds of PCs,
notebooks and servers, multiple networks) at our university and now we
are trying to migrate to Kea.

One thing we do in ISC DHCP is to use the "group" statement
in a subnet to set some parameters for a group of hosts at once.

subnet ... {

     ...

     group {
         next-server 10.1.0.101;
         option root-path "/srv/tftp";
         filename "/grub_bib_os_bookworm/x86_64-efi/core.efi";

         host bibkat01 { hardware ethernet 18:66:da:..:..:..; 
fixed-address bibkat01; }
         host bibkat02 { hardware ethernet f8:b1:56:..:..:..; 
fixed-address bibkat02; }

     }

     group {
         next-server 10.1.0.102;
         option root-path "/srv/tftp";
         filename "/grub_bib_os_bookworm_ed/x86_64-efi/core.efi";

         host bibkat03 { hardware ethernet f8:b1:56:..:..:..; 
fixed-address bibkat03; }
         host bibkat04 { hardware ethernet 98:90:96:..:..:..; 
fixed-address bibkat04; }
     }
}

I cannot find an equivalent option in Kea. Is it possible to do
something like this in Kea? I found that I can assign a client
class to a number of configuration parameters and then assign
this class to a host -- but this as far as I understand must
be done for each host separately. Same as with "option-data".

And I think that the "reservations" can only be defined once
in "Dhcp4" map.

We have eleven computer laboratories with at least sixteen
computers in each one. It is very convenient to set some
options to a group of hosts instead of each one individually.

Kind regards,
