Junos for IOS Users

The Junos OS command line interface (CLI) has many built-in tools to guide you while you master its commands and structure. If you already know a command language for another network operating system, such as Cisco's IOS, you can anticipate many of the Junos OS commands. Junos and IOS have two fundamental differences:

• Junos OS organizes commands in a structured hierarchy as opposed to a flat file, showing the configuration and commands of each level within its own set of curly braces {}.

  
  



• Junos OS stores changes into a candidate configuration instead of immediately affecting your active configuration file. You don't affect the active configuration until you commit the changes.

  
  

Because Junos doesn't use the ip keyword in the commands, many of the show commands you already know work if you simply drop the keyword. For example, show ip route becomes show route.
