hi All I’m using perfdhcp to test my kea-DHCP, while trying to produce DHCP requests via VLAN interfaces, the address allocation process doesn't end successfully.in the DHCP log I see all sessions end with "DHCP4_LEASE_ADVERT" message and no allocation accurse.
while using perfdhcp without VLAN the allocation accrues successfully. while using the VLAN interface with a single DHCP client (netplan not prefdhcp) allocation to the VLAN interface is successful. so it seems like when using the VLAN interface with prefdhcp the client doesn't claim the offered address. basically, I'm a bit lost here, so if someone has any idea what is happing here, it will be awesome. i hope I'm just missing an option in my perfdhcp command and not a limitation. attached debug log of the fail transaction. Thanks
