Additional Information
You can specify a regular expression as:

A period wildcard used in place of an AS number
•

You also can include the operators described in the table of AS path regular expression
operators in the
Junos Policy Framework Configuration Guide
. The following list summarizes
these operators:
•
{m,n}
—At least
m
and at most
n
repetitions of the AS path term.
•
{m}
—Exactly
m
repetitions of the AS path term.
•
{m,}
—
m
or more repetitions of the AS path term.
•
*
—Zero or more repetitions of an AS path term.
•
+
—One or more repetitions of an AS path term.
•
?
—Zero or one repetition of an AS path term.
•
aspath_term | aspath_term
—Match one of the two AS path terms.
When you specify more than one AS number or path term, or when you include an
operator in the regular expression, enclose the entire regular expression in quotation
marks. For example, to match any path that contains AS number 234, specify the
following command:
show route aspath-regex ".* 234 .*"
