Sample configuration files from the product documentation are available with the extension \*.sample.
Preconfigured YAML files, named with the prefix osp-ng-* are also available in the Git repository.
The sample YAML files are included for your convenience and preconfigured YAML files are made available for reference.
It is recommended to create your own YAML files using the sample configuration from the product documentation.
You may use the provided sample configuration in the lab to avoid copy-pasting from the documentation and refer to the preconfigured files for reference as needed.

For deployments in other environments, consider creating a table listing the necessary network isolation and their corresponding IP/subnet ranges to streamline the process.
