Statement introduced before Junos OS Release 7.4.
no-peer-loop-check option added in Junos OS Release 15.1.
When advertising AS paths to remote systems, have the local system strip private AS numbers from the AS path. The numbers are stripped from the AS path starting at the left end of the AS path (the end where AS paths have been most recently added). The routing device stops searching for private ASs when it finds the first nonprivate AS or a peer’s private AS. If the AS path contains the AS number of the external BGP (EBGP) neighbor, BGP does not remove the private AS number.
As of Junos OS 10.0R2 and higher, if there is a need to send prefixes to an EBGP peer that has an AS number that matches an AS number in the AS path, consider using the as-override statement instead of the remove-private statement.
The operation takes place after any confederation member ASs have already been removed from the AS path, if applicable.
Junos OS recognizes the set of AS numbers that is considered private, a range that is defined in the Internet Assigned Numbers Authority (IANA) assigned numbers document.
The set of reserved AS numbers is in the range from 64,512 through 65,535. The 32-bit private ASN scope is in the range from 4,200,000,000 through 4,294,967,294.
