During the IPv6 panel at the plenary last night, representatives of several major service providers discussed their experiences with IPv6. It became clear that many of their experiments involve technologies that delegate Provider-Aggregated (PA) IPv6 prefixes to the customer instead of Provider-Independent (PI) ones. This fact did not seem to be at the forefront of the service providers' use case considerations, and perhaps needs to be brought to a level of awareness in the community. Many years ago, there was an extended debate on this list regarding PA vs. PI. Emotions ran high, and in the end there seemed to be a consensus favoring PI. Have we forgotten about that? Is it time to re-open the debate? Thanks - Fred fred.l.templin@xxxxxxxxxx _______________________________________________ Ietf mailing list Ietf@xxxxxxxx https://www.ietf.org/mailman/listinfo/ietf
