When a router boots up, it follows a default order to search for startup configuration information. First, it checks the non-volatile memory (NVRAM) for the startup configuration file, typically named "startup-config." If it doesn't find a valid configuration there, it may look for a configuration file in a TFTP server, and if that fails, the router will proceed with its default settings, often leading to a mode where no configurations are applied.
