CARP assigns a special MAC address to the virtual IP: eg. from one of the HA firewall setups we manage at work: 00:00:5e:00:01:05 The last byte (05 in this case) is set to the VHID parameter you put on the ifconfig line to initialise the carpN interface -- eg. ifconfig carp0 inet 12.34.56.78 255.255.255.0 12.34.56.255 vhid 5 pass notTellingYou advskew 1 ^^^ If you have several pairs of systems on the same network all using carp, you need to ensure that they all use distinct vhid values or else chaos will ensue.
