The health of your ``keepalived`` instances can be automatically monitored via
|
|
a bash script that verifies connectivity to all available and configured
|
|
gateway addresses. In the event that connectivity is lost, the master router
|
|
is rescheduled to another node.
|
|
|
|
If all routers lose connectivity simultaneously, the process of selecting a
|
|
new master router will be repeated in a round-robin fashion until one or more
|
|
routers have their connectivity restored.
|
|
|
|
To enable this feature, edit the ``l3_agent.ini`` file:
|
|
|
|
.. code-block:: ini
|
|
|
|
ha_vrrp_health_check_interval = 30
|
|
|
|
Where ``ha_vrrp_health_check_interval`` indicates how often in seconds the
|
|
health check should run. The default value is ``0``, which indicates that the
|
|
check should not run at all.
