The issue is mentioned in: http://www.watersprings.org/pub/id/draft-arifumi-6man-rfc3484-revise-00.txt "2.5. To disable or restrict RFC 3484 Section 6 Rule 9 There was a discussion at v6ops and ietf@ietf.org mailing lists that the rule 9 of the destination address selection has a serious adverse effect on the round robin DNS technique...." However the above has expired. Perhaps Arifumi will issue a new version before the upcoming cutoff. -- Tim _______________________________________________ Ietf mailing list Ietf@ietf.org https://www.ietf.org/mailman/listinfo/ietf
