All,
You may remember that back in the mists of time (about a year ago) we
had a document that updated RIPE-399 with some IPv6 routing
recommendations. After the meeting last May, the authors were to go
away and take out mention of any specific suggestions on filtering (e.g.
/36).
Over the past 12 months, Philip and I have been hard at work constantly
refining this document to reflect the changing nature of the IPv6
routing table.
Well, kind-of.
Anyway, my laziness aside, appended is the document as it stands at the
moment. Comments and discussion please!
Rob
RIPE Routing Working Group Recommendations on IPv6 Route Aggregation
====================================================================
Rob Evans
Philip Smith
Introduction
============
Recent discussion has shown there is a limited requirement to be able
to advertise more specific prefixes from an IPv6 Provider Aggregatable
(PA) allocation where a Local Internet Registry (LIR) contains several
networks which are not interconnected, or for traffic engineering
purposes. This document recommends such advertisements are limited
in both length and scope. It is intended to supplement the working
group's Recommendations on Route Aggregation [RIPE-399].
Background
==========
The IPv6 address allocation and assignment policy for the RIPE
region [V6-ALLOC] only allows LIRs to obtain more than the minimum
PA allocation if they can demonstrate address utilisation that
requires it. This fits with the address space management principle
of conservation. However, as understood in the RIPE Routing Working
Group's Recommendations on Route Aggregation [RIPE-399], there are
occasionally requirements for the advertisement of more specific
routes from within an allocation. With a few ISPs currently filtering
at the minimum PA allocation (/32) within the relevant address ranges,
this can cause significant difficulties for some networks wishing to
deploy IPv6.
Some reasons for wanting to advertise multiple prefixes from a PA
allocation could be:
- The LIR has several networks that are not interconnected.
- Traffic engineering: A single prefix that covers an LIR's
entire customer base may attract too much traffic over a
single peering link
This document is only concerned with IPv6 Provider Aggregatable (PA)
allocations, and does not discuss Provider Independent (PI) prefixes.
Recommendation
==============
It is suggested that prefix filters allow for prudent subdivision of
an IPv6 allocation. The operator community will ultimately decide
what degree of subdivision is supportable, but the majority of ISPs
accept prefixes up to a length of /48 within PA space.
Advertisement of more specific prefixes should not be used unless
absolutely necessary and, where sensible, a covering aggregate
should also be advertised. Further, LIRs should use BGP methods
such as NO_EXPORT [RFC-1997], [AS-PATHLIMIT], or provider-specific
communities, as described in [RIPE-399] to limit the propagation of
more specific prefixes in the routing table.
Discussion
==========
There is a valid need for some LIRs to advertise more than one IPv6
PA prefix. As either obtaining more address space and advertising
more /32 prefixes, or advertising more specific prefixes within an
already allocated /32 have the same impact on the routing table,
it is suggested that the latter approach is taken to prevent address
space wastage.
It is understood that this may not cover all possibilities. There may
be circumstances where sites will have to consider the suitability of
Provider Independent addresses, or LIRs may have to consider
mechanisms of obtaining more than a /32 of Provider Aggregatable
space.

Dear Colleagues,
The RIPE NCC has received the IPv4 address range 185/8 from the IANA.
This is the final allocation of IPv4 address space that the RIPE NCC
will receive from the IANA as stated in ripe-436, "Global Policy for the
Allocation of the Remaining IPv4 Address Space".
The minimum allocation size for this /8 has been set at /22.
You may wish to adjust any filters you have in place accordingly.
More information on the IP address space administered by the RIPE NCC
can be found on our website at:
https://www.ripe.net/ripe/docs/ripe-ncc-managed-address-space.html
Additionally, please note that three "pilot" prefixes will be announced
from this /8. The prefixes are:
185.0.0.0/16
185.1.0.0/21
185.1.24.0/24
They all originate in AS12654.
The pingable addresses will be:
185.0.0.1
185.1.0.1
185.1.24.1
More information on this activity is available in the document
"De-Bogonising New Address Blocks", which can be found at:

Dear colleagues,
Prompted by a panel discussion at the RIPE 61 Meeting, this article by
Michael Behringer describes the most significant implications of network
complexity and suggests ways to deal with it:
http://labs.ripe.net/Members/mbehring/network-complexity-and-how-to-deal-wi…
This is a topic that requires more work and a lot of input from network
operators. We hope you will help to advance this subject.
Kind Regards,
Mirjam Kuehne

[Apologies for duplicates. Courtesy copy sent to Routing Working Group
and RIPE NCC Services Working Group. Please direct feedback to the
Address Policy Working Group mailing list.]
Dear Colleagues,
The new version of RIPE Policy Proposal 2008-08, "Initial Certification
Policy for Provider Aggregatable Address Space Holders", was published
on 9 February 2011. The time period for community review ends on 23
February 2011.
Some feedback was sent to the Address Policy Working Group mailing list.
However, to maintain the discussion, we strongly recommend that you
share your ideas and comments and clearly let the community know if you:
- Support the implementation of the proposal
- Support the general principle of the proposal but would prefer another
wording
- Support the general principle with some details changed but agree to
postpone this discussion until another stage of the policy proposal
review. (This is an initial proposal that covers only PA resources. If
the community supports extending certification to all resources, then
another version of the proposal will be necessary.)
- Do not support the proposal (please explain your motivations)
You can find the full proposal at:
http://www.ripe.net/ripe/policies/proposals/2008-08
and the draft document at:
http://www.ripe.net/ripe/policies/proposals/2008-08/draft
Please send an email with your comments to address-policy-wg(a)ripe.net by
23 February 2011.
Best regards,
