d. F= or one, no matter what I do with manually setting the state or adjusting the advskew, it doesn't work as expected. The same with the preempt kernel parameter. I have tried both unicast and multicast peer settings. Here are the configs: host1 $ ifconfig | grep 'vhid 10' inet 172.21.4.170 netmask 0xffffffff broadcast 172.21.4.170 vhid 10 carp: MASTER vhid 10 advbase 1 advskew 50 host1 $ grep 'vhid 10' /etc/rc.conf ifconfig_vmx0_alias10=3D"inet vhid 10 advskew 50 pass redacted alias 172.21.4.170/32" host1 $ $ export PS1=3D'host2 $ ' host2 $ export PS1=3D'host2 $ '^C host2 $ ifconfig | grep 'vhid 10' inet 172.21.4.170 netmask 0xffffffff broadcast 172.21.4.170 vhid 10 carp: MASTER vhid 10 advbase 1 advskew 100 host2 $ grep 'vhid 10' /etc/rc.conf ifconfig_vmx0_alias10=3D"inet vhid 10 advskew 100 pass redacted alias 172.21.4.170/32" host2 $ host1 $ cat /etc/sysctl.conf net.inet.carp.allow=3D1 net.inet.carp.preempt=3D1 net.inet.carp.log=3D1 Nothing has changed other than the OS version.
