Re: AW: Guidelines for Numbering IPv6 Point-to-Point Links and Easing the Addressing Plans

[Pekka Savola <pekkas@netcore.fi>]

Hi,

I read this short doc.  I don't believe it's necessary, but if there's 
something important there, it could be added to the addcon draft.

I believe the /48 assignment suggestion below is technically 
incorrect.  The ISP router, when it gets a packet destined to anything 
except the first /64 will inccorrectly try to use Neighbor Discovery 
to find the address, instead of forwarding it to the customer router. 
This can't possibly work unless the customer router is using proxy-ND.

=======
   Moreover, it is possible to use the shorter prefix as the provider
   side numbering for the point-to-point link and keep the /64 for the
   customer side.  In our example, it will become:

   o  Point-to-point link at provider side: 2001:db8:aaaa::1/48

   o  Point-to-point link at customer side: 2001:db8:aaaa::2/64
========
