Unfortunately where we have some of these routers, we don't necessarily have people in those locations... but what we DO have on the network is a "DHCP helper-address" to forward DHCP/BOOTP requests to a Kea-1.8 server (with the BOOTP hook library) as well as a TFTP server on the network.....

Literally just a few minutes ago I had the exact same thing happen. Since I have an SPF+ in the first slot, how exactly am I supposed to set this up for a net boot over the bootp protocol?
Also, why did my CCR1016-12S-1S+ brick the same day as someone elses with the exact same issue?
