While researching an RFC1997 issue this morning, I made the following observations:
CISCO no-export = RFC1997 NO_EXPORT_SUBCONFED CISCO local-as = RFC1997 NO_EXPORT
Cisco Press' Routing TCP/IP, Vol 2 explicitly states that LOCAL_AS == NO_EXPORT_SUBCONFED. It's description of LOCAL_AS differs, however, from the one you quoted from a Cisco web page: "LOCAL_AS (4294967043, or 0xFFFFFF03) -- RFC 1997 calls this attribute NO_EXPORT_SUBCONFED. Routes received carrying this value cannot be advertised to EBGP peers, including peers in other autonomous systems within a confederation." My money is on the Cisco web page you quoted being wrong.
