Editing Routing Policy Configuration Elements

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 the software for editing RPL policies:
• Nano (default)
• Emacs
• Vim
Editing Routing Policy Configuration Elements Using Emacs Editor
To edit the contents of a routing policy using the Emacs editor, use the following CLI command in XR EXEC
mode:
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:
