Community Members
These community-ids define one or more members of the community. They consist of two
components, which you specify in the following format:
as-number:community-value
as-number–AS number of the community member. It can be a value from 1 through 65,534.
You can specify the AS number in one of the following ways:
• AS number.
• Asterisk (*)–A wildcard character that matches all AS numbers. (In the defini-
tion of the community attribute, the asterisk also functions as described in
Table 1.)
• Period (.)–A wildcard character that matches any single digit in an AS number.
• Group of AS numbers–A single AS number or a group of AS numbers enclosed
in parentheses. Grouping the numbers in this way allows you to perform a
common operation on the group as a whole and to give the group precedence.
The grouped numbers can themselves include regular expression operators. For
more information about the community regular expressions, see Configuring
the Community Attribute Using UNIX Regular Expressions (See Using UNIX
Regular Expressions on page 480 and Examples of Defining Community
Attribute Regular Expressions on page 481).

• Period (.)–A wildcard character that matches any single digit in a community
value number.
• Group of community value numbers–A single community value number or a
group of community value numbers enclosed in parentheses. Grouping the
regular expression in this way allows you to perform a common operation on
