Configuration Template

Configuration templates provide a powerful way to define reusable configuration blocks that can be applied to multiple device groups with different variable values. This is particularly useful for service-related configurations that need to be deployed repeatedly across different devices or environments with slight variations.

Configuration templates work by:

Defining a template with parameterized values using ${variable_name} syntax
Applying the template to device groups via the configuration_templates attribute
Using device group or global variables to populate the template parameters

This approach promotes configuration consistency, reduces duplication, and simplifies management of similar services across your network infrastructure.
