While it is possible to copy the config directly into the startup-config and reload the router, I like to place it into running-config directly to make sure that everything comes up as it should. This pulls the configuration out of flash and makes it the current running configuration. (No password should be required if this is an unconfigured router.) Then use the following command to load the configuration from flash: When moving the configuration to another router, physically move the flash memory, power on the router, and answer “no” to the system configuration prompt. (I try to do it whenever I make a configuration change.)
(Just press Enter to continue.) This must be done on the old router. To copy the startup-config to flash as a file called backupconfig, use the following command: This simple command also provides a local backup copy of the router’s config which can save hours of work when replacing a dead router. Without this procedure, manually copying the old configuration to the new router will be necessary. When replacing a faulty router that is not completely dead, it may be possible to copy the startup configuration to the removable flash memory and swap the flash to get the new router up and configured in as short a time as possible.
