Hello list, When using (legacy ?) syntax ipv4_addrs_$interf="1.2.3.4/32" in /etc/rc.conf, CARP advertisements are sent from subsequent addresses defined using ifconfig_$interf_aliasN="2.3.4.5/32" This causes master-master situations and, obviously, network problems. I have attached a patch to the PR [1] which moves ipv4_addrs_$interf processing higher up the chain in /etc/network.subr Despite dating back from 2015 the patch applies just fine here on 10-STABLE and corrects the behaviour without any noticeable side effects. Seeking people running 9.x and 11.x to help close this PR [2]. Would anyone kindly check and report ?
