Let me try that once again! The authors have revised the text relating to the definition of the origin AS to be conformant to the current BGP specification, namely that if the AGGREGATOR path attribute is present it "contains the last AS number that formed the aggregate route" [RFC4271]. If this path attribute is not present the draft defines the origin AS as the AS preceding the AS_SET, which is a definition that has been drawn from the earlier WG mail thread on this topic
The intention here is not to impose criteria that differ from RFC4271, and define the origin AS in an manner that if an AS undertakes proxy aggregation in conformance with RFC4271 then this definition of origin AS will correctly identify the aggregator AS as the origin AS. This is slightly different from the various suggestions seen so far on the WG mailing list, but it is believed that this refines those suggestions in the light of a careful reading of the relevant sections of RFC 4271. The authors do not plan any further revisions of this document, and, accordingly, would like once more to request a WG Last Call of the -08 rev of the document. thanks, Geoff On 10/10/2010, at 9:50 PM, Geoff Huston wrote: > Hi, > > The draft's authors believe that the document > draft-ietf-sidr-roa-validation-07 is ready for WG Last Call, and in this note > we are requesting the WG Chairs to conduct such a WG Last Call. > > thanks, > > Geoff > > > On 08/06/2010, at 11:01 PM, Sandra Murphy wrote: > >> The WG LC has ended. >> >> There were no responses to this LC.
