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.
