Examples

Prerequisites:

As any new configuration will be made to the primary device, it is important to note the deploy: true value should present on the primary and deploy: false should be present on the secondary for Terraform to manage the deployment of changes from the FMC to the firewalls. If deploy: false is set for all devices, changes will need to be manually deployed after they have been sent to the FMC.

Interface configuration is performed after HA configuration, so interfaces under the vrf: key are only required on the primary. Secondary IP address information is configured via the ha_pairs: block shown below.
