I'm guessing this one (from the openBSD docs)...
net.inet.carp.preempt
Allow hosts within a redundancy group that have a better advbase and
advskew to preempt the master. In addition, this option also enables failing
over a group of interfaces together in the event that one interface goes down.
If one physical CARP-enabled interface goes down, CARP will increase the
demotion counter, carpdemote, by 1 on interface groups that the carp(4)
interface is a member of, in effect causing all group members to fail-over
together. net.inet.carp.preempt is 0 (disabled) by default.
But the FreeBSD man page doesn't talk about carpdemote
net.inet.carp.preempt Allow virtual hosts to preempt each
other. When enabled, a vhid in a
backup state would preempt a master
that is announcing itself with a
lower advskew. Disabled by
default.
At any rate what does "interface groups that the carp(4) interface is a member
of" mean?
Freddie, thanks for pointing me to this setting. Maybe the answer is in the
somewhere.
