Continue editing? [no]:
If you answer yes, the editor continues on the text buffer from where you left off. If you answer no, the
running configuration is not changed and the editing session is ended.
Editing Routing Policy Configuration Elements Using the Vim Editor
Editing elements of a routing policy with Vim (Vi IMproved) is similar to editing them with Emacs
except for some feature differences such as the keystrokes to save and quit. To write to a current file and
exit, use the :wq or :x or ZZ keystrokes. To quit and confirm, use the :q keystrokes. To quit and discard
changes, use the :q! keystrokes.
You can reference detailed online documentation for Vim at this URL: http://www.vim.org/
Editing Routing Policy Configuration Elements Using the CLI
The CLI allows you to enter and delete route policy statements. You can complete a policy configuration
block by entering applicable commands such as end-policy or end-set. Alternatively, the CLI interpreter
allows you to use the exit command to complete a policy configuration block. The abort command is
used to discard the current policy configuration and return to global configuration mode.
