The configuration that will be loaded on start up.
On NVRAM.
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.
That's where the router's startup-config (startup configuration) is stored.That's where the router's startup-config (startup configuration) is stored.That's where the router's startup-config (startup configuration) is stored.That's where the router's startup-config (startup configuration) is stored.
When a Cisco router is booted up for the first time, or is reloaded, the router will look into its Non-Volatile RAM (NVRAM) for the startup configuration file. Setup Mode is usedto configure a Cisco router or switch after start up to create a startup configuration file.
The startup-config file may be absent due to several reasons, such as the device being newly initialized, where no configuration has been saved yet. It could also be the result of a recent factory reset, which clears existing configurations. Additionally, if the configuration was manually deleted or if there are issues with the device's storage, the startup-config file may not be present.
The bash shell uses a hidden file called .bashrc for settings in the shell upon startup.
The startup configuration file on a Cisco router contains the configuration settings that are loaded into the router's memory when it boots up. It specifies parameters such as interface settings, routing protocols, access control lists, and other operational settings required for the router to function properly. This file is stored in the router's non-volatile memory (NVRAM), ensuring that the configuration persists even when the router is powered off. Essentially, it serves as the baseline configuration that the router uses to establish its operational state.
