Various embodiments of methods and systems for network infrastructure configuration based on network device configuration templates are provided. A network device configuration template is received where the network device configuration template corresponds to network device configuration data based on template elements. Template elements include variable placeholders, versions, Stock Keeping Units (SKUs), firmware, and target devices identified in the network device configuration template. Values for the template elements are referenced from a dataset storage component. The network device configuration data are classified into different classification units. The network device configuration data are merged with the network device configuration template that programmatically defines configuration of network devices. A network device configuration instance is generated based on evaluating the template elements and replacing template elements with values from the dataset storage. The network device can be associated with a configuration scope, where the configuration scope indicates intended configuration features of the network devices.
