Private AS Configuration
Private AS numbers are not advertised to the Internet. This command is used with exter-

vate AS numbers. If the update includes both private and public AS numbers, the system
treats it as an error.
To remove the private Autonomous System (AS) number from outbound updates, use the
following command.
