Cisco IOS XR Routing Configuration Guide
Editing Routing Policy Configuration Elements
RPL is based on statements rather than on lines. That is, within the begin-end pair that brackets policy
statements from the CLI, a new line is merely a separator, the same as a space character.
The CLI provides the means to enter and delete route policy statements. RPL provides a means to edit
the contents of the policy between the begin-end brackets, using a text editor. The following text editors
are available on Cisco IOS XR software for editing RPL policies:
• Nano (default)
• Emacs
• Vim
Editing Routing Policy Configuration Elements Using the Nano Editor
To edit the contents of a routing policy using the Nano editor, use the following CLI command in EXEC
mode:
edit route-policy name nano
A copy of the route policy is copied to a temporary file and the editor is launched. After editing, enter
Ctrl-X to save the file and exit the editor. The available editor commands are displayed on screen.
Detailed information on using the Nano editor is available at this URL: http://www.nano-editor.org/.
Not all Nano editor features are supported on Cisco IOS XR software.
Editing Routing Policy Configuration Elements Using the Emacs Editor
To edit the contents of a routing policy using the Emacs editor, use the following CLI command in EXEC
mode:
edit route-policy name emacs
A copy of the route policy is copied to a temporary file and the editor is launched. After editing, save
the editor buffer by using the Ctrl-X and Ctrl-S keystrokes. To save and exit the editor, use the Ctrl-X
and Ctrl-C keystrokes. When you quit the editor, the buffer is committed. If there are no parse errors, the
configuration is committed:
