A machine or a device with a known goes down, the failure will be detected and another device or machine is configured to take over the other's task by also taking over the other's MAC address. The communication partners will only a delay but not a failure. JKi: I'm curious, would, in your experience, the impact of any delay incurred by tinkering with addresses at both layer-3 AND layer-2 in a failover situation be less in comparison to any delay incurred when tinkering with the addresses at layer-3 ONLY and leave the recovery of addressing issues at layer-2 to the relevant protocols? Jk.
