Which command is used to load the rescue configuration?

While load override is a valid command for loading a configuration, rescue is not used as a direct keyword in this context for the rescue configuration.

The rollback rescue command is specifically designed in Junos OS to load the configuration that was previously saved using the save configuration rescue command. This command is used to quickly revert to a known stable configuration state.

There is no standard Junos OS command load replace rescue-configuration; load replace is used with a file or a configuration snippet.

rollback 49 would revert to a previous configuration version based on a numerical index, not specifically the designated rescue configuration.
