Command or Action Purpose
Step 1
edit {route-policy | prefix-set | as-path-set |
community-set | extcommunity-set {rt | soo} |
policy-global | rd-set} name [nano | emacs |
vim | inline {add | prepend | remove}
set-element]
Example:
RP/0/RP0/CPU0:router# edit route-policy sample1
Identifies the route policy, prefix set, AS path set,
community set, or extended community set name to be
modified.
• 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.
• 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.
• After editing with Vim, 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.
Step 2
show rpl route-policy [name [detail] | states |
brief]
Example:
RP/0/RP0/CPU0:router# show rpl route-policy
sample2
(Optional) Displays the configuration of a specific named
route policy.
• Use the detail keyword to display all policies and sets
that a policy uses.
• 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.
Step 3
show rpl prefix-set [name | states | brief]
Example:
RP/0/RP0/CPU0:router# show rpl prefix-set
prefixset1
(Optional) Displays the contents of a named prefix set.
• 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.
