I second this. I have several network switches that choke on the returned option.

Hello,

I'm using Kea 2.1.5

I'm working on a ZTP provisioning system for Junos devices.

In the kea config, I have NOT set up option 12 since I'll be providing hostname to the device via a ZTP config file.

I took a wireshark capture and noticed this behavior:

* In the ZTP process, the Junos device sends its S/N as option 12 in the DHCP discover. * Kea takes this option 12 and directly puts it back in the DHCP Offer message. * Junos uses this as its hostname instead of whatever I set in the config.

Is there a way to tell Kea to ignore whatever option it receives in DHCP discover message and not to set option 12 in the DHCP offer?

Thank you
