IPv6 Routing Recommendations.
by Rob Evans 04 Mar '11

04 Mar '11

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.

New IPv4 block allocated to RIPE NCC
by Andrea Cima 02 Mar '11

02 Mar '11

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 [Apologies for duplicate mails] 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: http://www.ripe.net/ripe/docs/ripe-351.html Kind regards, Andrea Cima Registration Services Manager RIPE NCC -----BEGIN PGP SIGNATURE----- Version: GnuPG/MacGPG2 v2.0.11 (Darwin) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iEYEARECAAYFAk1Pu9kACgkQXOgsmPkFrjM9FgCgsaT8cFxK0YKTFUFzj41L0PQT N1AAoIgmL1zUY8JjkCSa05xt0t8oppgP =woX5 -----END PGP SIGNATURE-----

[address-policy-wg] REMINDER; WAS Re: 2008-08 New Version and Draft Document Published (Initial Certification Policy for Provider Aggregatable Address Space Holders)
by Emilio Madaio 25 Feb '11

25 Feb '11

[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, Emilio Madaio

by Denis Walker 21 Feb '11

21 Feb '11

[Apologies for duplicate emails] Dear Colleagues, The RIPE NCC has implemented the "pingable:" and "ping-hdl:" attributes according to the specification in RFC 5943. They can now be used in ROUTE and ROUTE6 objects in the RIPE Database. RFC 5943 describes the syntax and explains how to use them: http://tools.ietf.org/html/rfc5943 The "pingable:" addresses are already active for beacons, anchors and debogon routes announced by the RIPE NCC Routing Information Service (RIS). For an example of how these are announced, see the ROUTE object for 84.205.81.0/24. For more information about RIS beacons and anchors, please see: http://www.ripe.net/data-tools/stats/ris/ris-routing-beacons Regards, Denis Walker Business Analyst RIPE NCC Database Group
