Re-,
Thanks Rajiv for the pointer.
BTW unlike the constraints we have in MAP (e.g., the bits forming PSID must be
adjacent), draft-cui-* and the like can use pseudo-random algorithms to
generate port ranges.

Hi Alain,
It's a little confusing now. Let me try to get things clear.
So the sd-nat-02 is not quite similar to the earlier version, the
mechanism somehow changes.
In my understanding, now the principle of the mechanism is similar to
the lightweight 4over6 draft, but I may miss something here.

Ole, Tomek,
I couldn't figure out by how CEs can be required to work hub-and-spoke without
some DHCPv6 indication:
- If two CEs apply the same BMR to their delegated IPv6 prefixes, how do they
know whether their ISP expects direct paths between them (mesh) or BR
hairpinning (hub-and-spoke)?

Hi Maoke and Remi,
Thanks very much for discussing this issue on the mailing-list. I guess the
points are now clear for both options. IMHO, there is no one better than the
other, it is all about choice of implementation. Perhaps it is time for more
people to comment how they feel for both

I am a little lost. Let's put the double-nat aside for a moment. Except
the fact that sd-nat uses icmp for port-set provisioning, what else
different between Lightweight 4over6 vs. sd-nat? Am I missing something?
For Lightweight 4over6, we can use anycast for redundancy. I fail to see
what sd-nat

in sd-nat, packets originated by an sd-CPE will be 'shaped' to use the
correct IPv4
Me too.
And another comment:
In sd-nat, it says More importantly, that draft (lightweight 4over6) does
not explain how this solution can be deployed in a regular DS-Lite
environment.
I think this is a deployment issue and lightweight 4over6 can definitely be
deployed in a regular DS-Lite

Behcet, I apologize. Even if we differ on what constitutes a multicast
solution, I was wrong to refer to your drafts in a pejorative manner.
