This Errata should be summarily rejected as there is no such reference in RFC 6823. Perhaps, it was reported against the wrong RFC. Thanks, Acee (as WG Co-Chair) On 6/16/22, 5:13 AM, "Lsr on behalf of RFC Errata System" wrote: The following errata report has been submitted for

UPAs may not even contain the advertised locator in SIDs. That is not clearly spelled out what exactly ABRs should advertise. I presume: a) something which was flooded in the local domain and was not being leaked AND b) something which stopped to be flooded in a local domain AND c) there is local

Hi Robert, Peter, Bruno You wrote: “Aas there is no association between node_id (perhaps loopback) and SIDs (note that egress can use many SIDs) UPA really does not signal anything about SIDs reachability or liveness. “ Sure, but UPA signals that a locator is unreachable, would that not result

Bruno, Actually I like your flag suggestion for an additional and different reason. If someone does not need to flood UPAs in any remote area it is trivial to filter those on the ABRs connecting those areas to the core. Otherwise such filtering could be more difficult if at all possible. Thx,
