Technical Summary
This document presents a review of mechanisms that could be used for
IPv6 site renumbering, analysing them for gaps in tools, protocols and
procedures. In undertaking the gap analysis, the document gives pointers
to future work that is required to improve renumbering operations, while
it also lists issues which it may not be possible to solve.
Working Group Summary
There is no significant controversy on the gap-analysis draft. Most
issues were teased out through review of the draft-ietf-6renum-enterpris
draft, which was recently sent to the IESG.
One gap that was identified in that review, which needs to be clarified
in 7.3, is that appropriate monitoring of the renumbering process is
needed to ensure it completes as intended, e.g. to look for old prefixes
in use.
There was some discussion as to whether "parameterised ip-specific
configuration" is the best phrase to use to talk about introducing wider
use of macros, etc. The phrase is a little clumsy, but no one as yet has
suggested anything better.
There was some discussion on DNS tools in the draft-ietf-6renum-
enterprise review. In particular about wider deployment of Dynamic DNS
support. This illustrates that some gaps are due to lack of deployment
of tools that *could* be used, but are not due to that lack of
deployment.
It may be useful to add a section listing the identified gaps more
explicitly; the work that has been identified to date is captured in
draft-carpenter-6renum-next-steps-00 (which is not intended to be taken
forward, rather be an inventory of work items to progress
appropriately).
There was some discussion of router renumbering. RFC2894 is old (August
2000) and has not as far as we're aware been used, and it is unlikely
that it would ever be used. A more appropriate approach may fall under
'Unified Configuration Management' as described in 6.3. A small
clarification may be beneficial.
Note revision due to IETF last call comments is the 06 version.
Document Quality
There has been a reasonable number of reviews for a document of this
type, which have led to it being in its fifth version since WG adoption.
I have notified the authors of a small number of grammatical errors,
which will be processed along with IESG comments.
