This object strips private AS numbers from the AS path advertised to this eBGP neighbor when enabled; it has no effect on iBGP peers. Administrators enable this when redistributing routes that were originally tagged with a private AS internally, to avoid leaking non-routable AS numbers to external peers. For example, an engineer enables csBgpNbrRemovePrivateAs for a transit provider peer so that internal private-AS path segments used within the customer's own confederation aren't exposed externally.
