+> [!NOTE]
+> This module defines custom types (`network_config` and `network_route`) that require proper plugin synchronization. If you encounter errors like "Could not autoload puppet/type/network_config", you may need to run `puppet generate types` on your Puppet server (for Puppet 6+) or `puppet plugin download` (for older versions).
