as-path-set | community-set |
Step 1
extcommunity-set { rt | soo } |

A copy of the route policy, prefix set, AS path set, community set, or
extended community set is copied to a temporary file and the editor is
launched.
policy-global | rd-set } name [ nano |
emacs | vim | inline { add | prepend |
remove } set-element ]
Example:
RP/0/RSP0/CPU0:router# edit
route-policy sample1
•
After editing with Nano, save the editor buffer and exit the editor by
using the Ctrl-X keystroke.
•
After editing with Emacs, 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.

(Optional) Displays the configuration of a specific named route policy.
show rpl route-policy [ name [ detail ] |
states | brief ]
Step 2
•
Use the detail keyword to display all policies and sets that a policy
uses.
Example:
RP/0/RSP0/CPU0:router# show rpl
route-policy sample2
•
Use the states keyword to display all unused, inactive, and active
states.
•
Use the brief keyword to list the names of all extended community
sets without their configurations.
(Optional) Displays the contents of a named prefix set.
show rpl prefix-set [ name | states | brief

To display the contents of a named AS path set, community set, or
extended community set, replace the prefix-set keyword with
as-path-set , community-set , or extcommunity-set , respectively.
Example:
RP/0/RSP0/CPU0:router# show rpl
prefix-set prefixset1
