[address-policy-wg] late comments on 2009-06

Dear colleagues,

the last call for 2009-06 is very close to expiring...
I'm sorry I'm coming this late with a few comments.

I certainly support the the motion to remove from the contraints for
routing announcements from the address allocation policy; I voiced
my support already at the last RIPE meeting with strong words.

I hope that Rob Evans' initiative to draft a document on recommended
annoucement practices in IPv6 in routing WG will result in document
providing guidance on usage of aggregates, more specifics etc. without
unduely stressing the global routing system.  Admittedly this will be
much harder than the removal of a few words from existing policy text
(as 2009-06 does).

Recently a potential downside of the removal of routing constraints from
allocation policy came to my attention:  NCC resource analysts might begin
to encourage or even force LIRs to plan to deaggragate announcements
when discussing requests for address space.

For the record: I'd strongly request that NCC should refrain from doing so
until documents giving guidance on appropriate use of deaggregation,
or announcements of more specifics have been written and agreed upon.
Applying such restraint seems not to require explicit text in the allocation
policy - though I can see that NCC using or not using such restraint
can in some cases lead to different results in evaluating requests for
address space; i.e. some times allocating an additional separate address block
when using a more specific out of another allocation might be another way
for solving a particular routing requirement.

Before closing let me make another nit: I feel quite uncomfortable to see
the the second paragraph the impact analysis for fragmentaion/aggregation:
it would be better to ONLY have the "we cannot seriously estimate" of the
first paragraph than juggle meaningless short sighted numbers.


Regards,
  Ruediger
