Dear list,
I am currently setting up two 4.6 boxed to act as carp'ed firewalls.

% sysctl net.inet.carp.log

Even though I got to quite satisfying results, I am confused about the
net.inet.carp.preempt definition given in the carp(4) man page:
a) Allow virtual hosts to preempt each other.
b) It is also used to failover carp interfaces
as a group. When the option is enabled and
one of the carp enabled physical interfaces
goes down, advskew is changed to 240 on all
carp interfaces. See also the first example.
Disabled by default.
I have no problem to observe [a], but I really can't manage to make [b] happens.
So when one of my interfaces goes down, all carp interfaces are
failing over to the other node but it seems to be thanks to the
demotion of "carp" group. A you can see below, advskew on the other
hand does not change at all:
-------------------------------------

Apr 13 16:15:13 bsdfw1 /bsd: carp0: state transition: MASTER -> BACKUP
The failover happens and it comes back almost instantly if I up vlan2
back, and I would be quite happy with that if there wasn't this
statement in the manpage about advskew being supposed to change.
I tried different things to see it happen (disabling interface at the
switch level, using the raw interface instead of vlan) but to no
avail.
Would anyone be so kind as to explain me what I am misunderstanding here ?
Thanks, and regards,
William
