[address-policy-wg] 2014-03 two cents on multi homing ASN requirement

Dear all,

Based on the feedback from the working group we have developed a
new iteration of the proposal.

Concerns addressed:

- remove private AS Number reference (Fredy Kuenzler, 1 May 2014; Alex
    le Heux, offlist; Erik Bais, offlist)
- differentiate between 16 and 32 bit ASN (Nick Hilliard, 1 May 2014;
    Aleksi Suhonen, 14 August 2014; RIPE NCC Impact analysis section B
    "Autonomous System Number (ASN) Consumption")
- Specify timeline when multihoming is required (Janos Zsako, 11 Jul 2014

What has not been addressed is the creation of an exhaustive list of
acceptable reasons to request an ASN. The authors do not know how to
update (without full PDP process) the list when new technologies or
methodologies arise. Rather, the authors believe that RIPE NCC is
responsible for maintaining an accurate registry than evaluate network
designs. In a years time the RIPE NCC could publish an aggregated report
on the recorded needs, possibly to inspire the community to reconsider
this policy.

----------------- replaces section 2.0 from RIPE-525 -----------------
2.0 Assignment Criteria

A new AS Number should only be assigned when the End User expresses a need
that cannot be satisfied with an existing AS Number. RIPE NCC will record,
but not evaluate this need.

When requesting a 16 bit AS Number, the network must be multihomed using
the assigned AS Number within 6 months. A 32 bit AS Number is exempt from
the multihoming requirement.

When requesting an AS Number, the routing policy of the Autonomous System
must be provided. The new unique routing policy should be defined in RPSL
language, as used in the RIPE Database.

The RIPE NCC will assign the AS Number directly to the End User upon a
request properly submitted to the RIPE NCC either directly or through a
sponsoring LIR. AS Number assignments are subject to the policies described
in the RIPE Document “Contractual Requirements for Provider Independent
Resource Holders in the RIPE NCC Service Region”.
