Configuring an AS Path (policy-option)
An AS path is defined by a regular expression in the config>router>policy-
options context. Once defined, it can be added, removed, or replaced in a policy statement
as part of a default action, an entry action, or an entry from (source) definition. See
Configuring a Default Action
The following example displays as-path command usage.
A:ALU-B>config>router># info

A:ALU-B>config>router>#
Configuring a Community List
Community lists are composed of a group of destinations that share a common property.
Community lists allow you to administer actions on a configured group instead of having to
execute identical commands for each member.
The following example displays a community list configuration:
A:ALU-B>config>router>policy-options# info
