CARP sends advertisements using multicast by default, but can be configured to use uni-cast announcements to a specific peer via the peer and peer6 parameters. Why unicast ? Multicast is not always reliable in modern network environments, especially in virtualization where multicast traffic may be filtered, limited, or improperly forwarded. Steps : [x] 1. Add the parameter "peer" manually [x] 2. Verify CARP peer communication [] 3. Automate the peer configuration with Salt [] 4. Verify CARP peer communication

CARP sends advertisements using multicast by default, but can be configured to use uni-cast announcements to a specific peer via the peer and peer6 parameters. Why unicast ? Using CARP in unicast mode can be appropriate in a two-router topology, as communication only needs to occur between 2 specific peers and also multicast support is often filtered, limited, and so unreliable. Steps : [x] 1. Add the parameter "peer" manually [x] 2. Verify CARP peer communication [] 3. Automate the peer configuration with Salt [] 4. Verify CARP peer communication
