Hi all,

We use the DHCPv4 Option 82 (Circuit ID) to RADIUS lookup functionality to authenticate most of our users.

While DHCPv6 on MikroTik has had a lot of improvements lately, it doesn't appear that DHCPv6-PD requests use Option 18 (Interface-ID) when doing a RADIUS lookup. I've done packet captures and can confirm that I'm receiving the option in the DHCP discover, but it's not included in the RADIUS request.

Google has not helped me with this, it only highlighted that a few other vendors support this functionality. Has anyone done any investigations into doing this on MikroTik? Is it on the roadmap, or is there an option I've missed? I'm happy to log a ticket to support but I didn't want to bother them if I'm just missing a tickbox somewhere.

Regards,
Philip
