Hi Pietro,

I tried configure your case in linux enviroment. I didn't get configured value in dhcp response, but when I use dhcp6. prefix (maybe namespace) before configured variable,  i at least part of response (without value).

option dhcp6.my-option code 64 = string; (maybe use ip6-address type of variable)

subnet6 2001:100::64 {
...
option dhcp6.name-servers 2001:100::1;
option dhcp6.my-option aa:11:22:33;
}

Maybe this is the way.

Regards
Michal.
