Command History
Usage Guidelines
Use this command to provide a list of AS numbers or an AS-path access list using a regular expression.
BGP uses this match criteria to determine the BGP peers that will be used to create a BGP session.
Use the route map to specify a range of AS numbers whose peers can establish a session with the local
BGP through prefix peering. Cisco NX-OS ignores any other
match
commands if the
match as-number
command is present in the route map.
This command requires the LAN Enterprise Services license.
