Configuration File Storage

The primary and standby RPs maintain and distribute the configuration files for every card in the router.
These files are in "native" format and cannot be browsed by the user. Configurations can be managed

Note Recent running configuration files are stored in the /cfsroot directories on the internal flash disk0:.
Access these configurations only through the CLI commands for configuration management, history, and
