Usage Guidelines
Private AS numbers are AS numbers in the range 64512 through 65534. You can remove private AS
numbers from the AS path attribute in updates that are sent to external BGP (EBGP) neighbors. Possible
reasons for using private AS numbers include:
The remote AS does not have officially allocated AS numbers.
●
You want to conserve AS numbers if you are multi-homed to the local AS.
●
Private AS numbers should not be advertised on the Internet. Private AS numbers can only be used
locally within an administrative domain. Therefore, when routes are advertised out to the Internet, the
private AS number can be stripped out from the AS paths of the advertised routes using this feature.
Example
The following command disables the removal of private AS numbers from the AS path in route updates
sent to the EBGP peers:
disable bgp neighbor 192.168.1.17 remove-private-AS-numbers
