The most important points are as below –
Both the Master and Slave must share the same Group number value.
The “Role” value of the Master device is different from that of the Slave device.
Both the Master and Slave must share the same Virtual IP value.
Master Failure / Shutdown
Once the Master unit is shut down or fails, Slave would be switched from idle state to
active state after 3 to 4 seconds and then take over Master.
Master Restart
Once Master is back to normal, and then Slave will be restored to be idleness.
