Hi Chris,
reading the draft, it seems clear that it is bound to your specific
CableLabs eRouter use case.
I haven't understood if this is just an informational draft, or whether
you want to pursue it further and adapt the draft to create a standard.
In the latter case, some thoughts:
It's not clear, that it would work with all the scenarios outliend in
section 3.2.2 of the homenet architecture
(http://tools.ietf.org/html/draft-ietf-homenet-arch-07).
E.g. how does it cover Multihoming? If an internal router gets two
addresses, one from each prefix, and assuming no CER_ID, how do you
ensure that the /48 check works, and it doesn't pick the first address,
comparing it to the second prefix, and thus declaring the router a CER
which it is not?
I believe that's a non-issue, as the /48 check is done on a
per-interface basis, but that's not documented in the draft.
A multihoming section where you explain this, would be beneficial I think.
I also don't like the "/48 check" notation, as it implies that ISP's
hand out a /48 (even if stated otherwise in the text).
If you call it "ISP prefix check" or "Delegated prefix check" would be
better, as the principle is, that the ISP hands out an address to the
CER which is different from the delegated prefix, while the CER hands
out addresses from that prefix.
Cheers,
Mat

Dear Homenet,
CableLabs, in cooperation with our members and vendor companies, is
enhancing our eRouter specification to support multirouter home networks.
As we have in the past, we are presenting our eRouter updates to the IETF
in the spirit of sharing. We believe that these enhancements meet the
principles of the homenet-arch document, while not relying on new protocol
development.
In addition, we are prototyping these enhancements, and are planning to
demonstrate them in Orlando.
Cheers,
~Chris

Abstract:
Home networks are becoming more complex. With the launch of new
services such as home security, IP video, Smart Grid, etc., many
Service Providers are placing additional IPv4/IPv6 routers on the
subscriber network. This document describes a self-configuring home
router that is capable of operating in such an environment, and that
requires no user interaction to configure it. Compliant with
draft-ietf-homenet-arch, it uses existing protocols in new ways
without the need for a routing protocol.
