Hi,

 during the v6ops meeting, Dave (and maybe others) brought up an issue
 about the support for other protocols, like MIPv6, SCTP, DCCP and others.

 Curerently the draft is phrased as follows:

   I6: MIPv6 support

   The translation mechanism SHOULD not prevent MIPv6 Route Optimization
   when the CN is a v4-only node



GT> I am confused about this one. MIP6 RO requires the CN to
participate in MIP6 signaling for the Return Routability tests. How
would an IPv4 only node participate in such an IPv6 specific
signaling?. This makes no sense to me.
Well, what people have suggested is that you can perform the RO to the NAT64 box (i.e. the NAT64 perfomrs CN operations on behalf of the v4 node) 



I was also thinking if any other MIP related scenario is worth
considering here, e.g., MIP HA inside vs outside the NAT64. MIPv4 and
MIPv6 protocols, however, are entirely incompatible so MIPv4 to MIPv6
translation is not a realistic option as far as I can tell. My
inclination is to just forget about Mobile IP and all its versions and
denominations for now.


i am ok with that too

Regards, marcelo
