Later, SnapGear unit #1 comes back online as the slave. SnapGear unit #2 continues its
role as the default gateway for the local network.
Note
Using the default high availability script, a high availability failover is not triggered by the
master simply losing Internet connectivity. The master must become uncontactable to
the slave via the local network segment for an HA failover to be triggered.
Enabling high availability
On each of the devices, click Network Setup, Failover & H/A, then the High
Availability tab.
Click New. Select Check this interface. From the Nework Interface dropdown select
the interface that you will be ‘checking’. In the IP Address field, enter the shared-IP
address and click Finish.
The share-IP address will automatically be configured as an alias interface by the HA
script and logic on whichever device is currently the master device. More sophisticated
HA scenarios can be configured by setting up a basic configuration here and then
manually editing the ifmond.conf file and the scripts it calls.
