HA Components
The HA components are listed and described below.
CARP:
Keeps updated on the health of the partner
Governs whether the LoadMaster will take the active role
The
Use for HA Checks
option enables CARP requests to be sent over enabled interfaces.
This can be set for multiple interfaces.
When CARP is being used, packet analysis tools such as Wireshark,
incorrectly displays the protocol used as Virtual Router Redundancy
Protocol (VRRP). Any IP addresses displayed by the packet analysis tools
are fictitious and are not part of the CARP protocol.
Sync:
Sync maintains a “single image view” of the LoadMaster settings. It keeps the
LoadMaster up-to-date with changes made to Virtual Services and all other
configurations.
Notable exceptions that are not synchronized are; time and passwords
Keeps the standby LoadMaster updated on persistence updates
