Parameters
• name — Enter the access list name (1 to 140).
• ASNumber — Enter the AS number.
Defaults Not congured
Command Mode CONFIGURATION
Usage Information
You can specify an access list lter on both inbound and outbound BGP routes. Each lter is an access list based
on regular expressions. If the regular expression matches the representation of the AS path of the route as an
ASCII string, the permit or deny condition applies. The AS path does not contain the local AS number. The no
version of this command removes a single access list entry if deny and a regexp are specied. Otherwise, the
entire access list is removed.
Example
OS10(config)# ip as-path access-list abc deny 123
Supported Release 10.3.0E or later
