Carp configuration errors

[Ask Bjørn Hansen]

Hello,

After upgrading to 9.1 it seems like carp doesn't pay attention to advskew anymore.  I have two boxes each setup with carp0 and carp1; the intention is that in regular operation proxy1 is master for carp0 and proxy2 for carp1. However, whichever box comes up second is BACKUP for both.

To make IPv6 CARP work I am using the patch from http://www.freebsd.org/cgi/query-pr.cgi?pr=127050

I don't know if it is related, but when booting I see a lot of messages like

ifa_del_loopback_route: deletion failed
ifa_add_loopback_route: insertion failed
ifa_del_loopback_route: deletion failed
ifa_add_loopback_route: insertion failed
ifa_del_loopback_route: deletion failed
ifa_add_loopback_route: insertion failed
ifa_del_loopback_route: deletion failed
ifa_add_loopback_route: insertion failed

in dmesg.

I am including my rc.conf files for each host below. Any hints or suggestions will be appreciated.
