Objects and templates created by the SD-WAN overlay template
The SD-WAN overlay wizard automatically creates templates and objects required for deployment of SD-WAN in your environment. Generated templates and objects are assigned to the hub(s) specified by the template, and branch devices are identified by membership in the specified device group. See Configuring an SD-WAN overlay template.
The following template and objects are created by the SD-WAN overlay template wizard:
- IPsec templates
- BGP templates
- SD-WAN template configuration
- CLI templates
- Templates groups
- Metadata variables
The SD-WAN overlay template wizard also configures the SD-WAN overlay network. The default overlay network used by the wizard is 10.10.0.0, but this can be configured for your environment. The number of subnets created from the overlay network depends on the number of overlays and hubs that are configured.
Below details the various templates and associated components that are defined in dual-hub and single-hub deployment scenarios.
