Hi Boucadair, I'm wondering if I have missed something in this draft. I can understand that in this extended DS-Lite, ICXF is core stateless and it is quite scalable for core routers. However, since CPEs can send both IPv4 packet and IPv6 packet to AFTR, it will then include double NAT problem if we have to allocate private IPv4 address to CPEs. Then what is the advantage of this kind of DS-Lite vs. NAT666 plus dual stack?
Thank you very much. Best regards Qiong SUN
