Dear all, I really don't understand this issue. It is even misplaced to have this comment at this stage, since this is a document which has been adopted by the WG and the solution it specifies is the same as the one reviewed by the WG prior to its adoption (i.e., since April 2011). Anyway,

Woj, I am confused. You said given that EA=0 is already covered (eg embedding of full IPv4 address, no address sharing, if not the other case). If I read the spec right, this is my understanding: If I want to embed full v4 address in the CE v6 address, the v4 address will be embedded in the EA.

Woj, The argument you are raising applies also for (1) and (3): one can argue this justifies editing an RFC6333-bis to cover the per-subscriber state case ;-) As I mentioned in my first message, MAP can be extended to cover the per-subscriber case at the cost of adding confusion by abandoning

Med, the point is that the DS-Lite (CGN AFTR) solution is not necessary to be deployed for the multicast solution described here to work. As to how this ended up being charterd in Softwire I don't know and IMO it doesn't make much sense. Regards, Woj. On 27 July 2012 13:48,

Ole's and Satoru's eaerlier replies on this thread described the how, and even Maoke's earlier post on this thread acknowledged EA=0 with full IPv4 to be a naturally established case of the MAP. EA=0 simply means that there isn't IPv4 (or PSID) info in the IPv6 prefix. In terms of your

Re-, Yes, the CGN is not required. This design choice is motivated in the draft (read the Introduction text). What is the issue then? If you are saying this is a generic solution and it does not apply only to ds-lite, this point is taken (see the note below). Cheers, Med

Woj, According to your description, it is clear that the way to deal with EA=0 is quite different with EA0. Mixing them together will not only make MAP losing the initial no state in the ISP network paradigm spirit, but also make MAP a lot more complex and confusing. Actually, the use case for
