deny: Specifies the match mode for the AS path list as deny.

regular-expression: Specifies the AS_PATH regular expression, a string of 1 to 50 characters.
BGP routing updates contain the AS_PATH attribute field that identifies the autonomous systems through
which the routing information has passed. An AS_PATH regular expression, for example, ^200. *100$,
matches the AS_PATH attribute that starts with AS200 and ends with AS100. For the meanings of special
characters used in regular expressions, see Getting Started Guide.
