Hi Qi, Thanks for the clarifications. I still think that having a DMR option for MAP would more clear, but if the WG has decided to re-use the DS-Lite AFTR Name option I’m ok with that as long as it is used as designed. Regards Roberta

There was a proposal and a long discussion on the dhc working group about to be able to use the same option to provision either the name or the address but the wg did not reach consensus on that idea. So in my understanding you cannot carry an IPv6 address into the DS-Lite AFTR Name option [Qi] Sorry for not expressing it correctly. My intension was that the DS-Lite AFTR Name option could be used to tell the CE the BR's IPv6 info. The option should be used as it is designed. I didn't try to change that. it would sound confusing in my opinion, using a DS-Lite specific option to provision MAP specific parameters. [Qi] In the Unified CPE draft, it using the DS-Lite AFTR Name option to provision the IPv6 info of BR. The map dhcp draft is going to remove the DMR option. So I think these drafts should be aligned.
