Show running-config
You want to totally reinitialize the router and replace the current running-config with the current startup-config. What command will you use?
wr or copy running-config startup config
NVRAM
To save the running configuration on a router, you typically use the command copy running-config startup-config in the privileged EXEC mode. This command copies the current configuration stored in RAM (running-config) to NVRAM (startup-config), ensuring that the configuration is retained after a reboot. Alternatively, you can use the shorthand command write memory. Always confirm the save by checking the startup configuration with the show startup-config command.
Router(config)#Copy running-config startup-config
**Switch-6J#
The IOS command to copy the running configuration to NVRAM is copy running-config startup-config. This command saves the current configuration in RAM (running config) to the non-volatile memory (NVRAM), ensuring that the configuration is preserved after a reboot. You can also use the shorthand version, wr or write memory, to achieve the same result.
