Dear Qiong, Thank you for reading the ID.
As far as the CPE is concerned, this ID assumes the same behaviour as per DS-Lite architecture documented in draft-ietf-softwire-dual-stack-lite. In particular, no NAT44 is enforced in the CPE and therefore no double NAT would be experienced. Cheers, Med ________________________________ De : [email protected] [mailto:[email protected]] De la part de ??

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.
