Re: [v6ops] Comment on 'draft-ietf-v6ops-unique-ipv6-prefix-per-host-07'

[David Farmer <[e-mail]>]

I don't think you can just plop that in there without at least some
revisions to section 4 as well.

Thinking about this a bit, I think you are referring to redirects in
general and your draft 'draft-templin-6man-rio-redirect' more specifically.
In a current unmodified host only individual addresses and not whole
prefixes can be redirected, and therefore the router would have to track
individual addresses to redirect them, which again break the premise of
reducing ND.  Once redirects for whole prefixes are commonly available then
at the discretion of the router you could do as you suggest.

While I like the ideas in 'draft-templin-6man-rio-redirect' they are not
generally implement in the vast majority of hosts today, and therefore
networks implementing 'draft-ietf-v6ops-unique-ipv6-prefix-per-host' can't
reasonably expect the capability to be available, and can only reasonably
expect redirects for individual addresses, and implementing peer-to-peer
communication on that basis is not compatible with the fundamental
expectation in 'draft-ietf-v6ops-unique-ipv6-prefix-per-host'.

Once the capabilities described in 'draft-templin-6man-rio-redirect' are
generally available, I think it would be reasonable to add an option for
peer-to-peer communication to a future revision of
'draft-ietf-v6ops-unique-ipv6-prefix-per-host', but based on the
capabilities available today you can't implement peer-to-peer
communications without violating other fundamental expectations in
draft-ietf-v6ops-unique-ipv6-prefix-per-host'.

Thanks.
