#70 DHCP Failover With NTP

In this episode Dorothy and I try to understand the ISC DHCP server fail over configuration. There are two servers, primary and secondary. The servers work in a load balancing configuration by splitting the subnet in half. We understand that part. The rest is a confusing mix that we're not sure we get at all. Talking about the options helps. A DHCP failover setup requires accurate time. That's where NTP comes in. While we haven't configured our DHCP failover setup yet, we did manage to install NTP. It's a small step in the right direction.
