Multiple Slaves
There should be only one Master, but multiple Slaves are allowed. Generally speaking,
the Slave with the greater LAN IP address will have higher priority to play the role of
Master if the original Master is shut down or fails. For example, the IP address
192.168.1.4 will have higher priority over 192.168.1.3.
Reference
The HA function was developed based on VRRP (Virtual Router Redundancy Protocol).
For further detailed information about VRRP, please refer to RFC 2338.
