RE: [savi] Broadband Forum liaison to IETF on IPv6 security

["Hemant Singh (shemant)" <shemant@cisco.com>]

I agree with Thomas.  The reason I and Wes could reply with some ideas
is because we are familiar with the cable deployment and contributed
text for ND Proxy behavior in cable standards.  A start for diagram may
be RFC4779 that DSL folks should look at and tell us what they talking
about.  If a DSL deployment doesn't exist in RFC4779, then for long-term
one should bis RFC4779 to include the new DSL deployment so that all can
reference a common doc and discuss deployment problems for IPv6.

This is too skimpy of problem statement for me to understand the
details of the problem.

I don't know that a lot is needed. Maybe 2-3 pages is enough. But show
me a diagram, label the pieces, show me the properties of the pieces
and explain what the *exact* problem is. Who needs to do DAD? Why
doesn't it work? etc.

And note that comments like (quoting from the above statement):

  "We can envision a number of scenarios, both malice or vendor
   incompetence by which this can happen."

There is very little anyone can do to prevent "vendor
incompetence". I hope you aren't asking the IETF to solve this
problem! :-)
