Dear Experts,
I was running ISC DHCP server for longer than I would care to remember. Now I decided to climb out of the cave and configure failover set (primary-secondary), and I seem to hit brick wall, which I need help with. I only need IP v4, no v6, which may simplify things.
Could someone point to a description of working DHCP failover configuration?
I wrote this article a long time ago:

It worked for me at my last job.
