Hi Alexey!

 RM>> With 1 v6 subnet it is easy, you just announce the subnet.

Yeah ... this is what I tried to say.
If you have 1 /64 you deal with it easily also in the dumbest router.
If you have multiple subnets you need a way to configure which subnet is announced where.
This makes it more complicated.

 RM>> If you allow more, you need a way to configure them. (eg. VLANs,
 RM>> different subnet on different LAN port, etc.)
 AV> Or simply route more /64 subnets through that address. Or /56 at once.

This is not really beneficial.
From my point of view it makes only sense if you can split them up into multiple different subnets.
And for 95+% of people it makes no difference, or they do not care.
So ISPs say that this is a business feature, that is only supported by more expensive routers and more expensive ISP services.

 RM>> That is added complexity for a low cost product, where most of
 RM>> your residential customers will have no clue what this is all
 RM>> about. So it makes more sense to offer that on higher tier (and
 RM>> more expensive) services.
 AV> That violates the KISS principle.

Yes, and that is exactly the reason why there is only one /64.
Keep it simple.

CU, Ricsi
