Re: new draft on IPv6 CPE router available for review

Especially, Mikael, how do you fix it ? This is still you have not answer yet.
I don't write RFCs. I don't really read them a lot either, just when I absolutely need to. On the other hand, I know a lot about router architecture and network operational issues and I know what I think would be the best operational situation to have for IPv6 in 10 years, and that's why I'm advocating the solution I'm advocating.
If you want to remove the merit of my proposal on the basis that I haven't supplied RFC quality text to support it, well, then the IETF process is broken because it doesn't listen to what the operational community has to say. I am supplying operational input here, not RFC proposals. 


Even if some ISP does not do assign global IPv6 address to the CPE,
that's up to that ISP.
If the draft doesn't put a strong emphesis on the POSSIBILITY of not assigning a WAN IP address (and how this case should be handled), most vendors will not implement it. 


But their customer should be noticed that some machine which is compatible
IPv6 standard specification can not work correctly if that terminates upsteam link.
I have no problem with that. Services always has restrictions and specifications. 


Again, so I like the following original text of draft-wbeebee-ipv6-cpe-router-00.txt

-------------------------------------------------------------------------------------
5.3.  Acquire IPv6 address and other configuration parameters

  The CPE Router must process RAs received on the WAN interface and as
  instructed by the RA message, acquire global IPv6 address for WAN
  interface using SLAAC or DHCPv6.
-------------------------------------------------------------------------------------
I have no problem with this, apart from that it doesn't say what should be done if there is no WAN address received.
I am not saying your solution shouldn't be done, I'm saying I want the possibility of both, and if these aren't included in material like this draft, my proposal won't be realistically possible anytime soon.
