AOB ======================== A: Scribe, Agenda bashing ======================== Two scribes from the RIPE NCC. One additional presentation from the tipster project was accepted for point K on the agenda. The Agenda was accepted. ======================== B. IPv6 roadmaps of network equipment vendors a. Juniper ======================== Jean Marc Uze (JMU) presented Junipers Roadmap for IPv6. The slides are available at: http://www.ripe.net/ripe/meetings/archive/ripe-42/presentations/ ripe42-ipv6-juniper.pdf Pim van Pelt (PVP): What about Filtering and OSPF6 ? JMU: OSPFv3 for Junos will come in the second half of 2002 Filtering will come in a couple of weeks. ?: Are you working on 6-to-4 transition? JMU: Are there already applications that need it? ?: 6-to-4 relays will need it, these will be important for the users ?: What about 6PE? (MPLS over IPv6) JMU: Should be avoided on core routers, since it degrades performance. ?: Will you implement NAT/PAT for v6? JMU: Not on the short term. 6to4 as well as other mechanisms like NAT-PT are under investigation but we didn't get a strong push from our customers so far. Inviting the vendor to the RIPE IPv6 WG is a good way to discuss this topic. ======================== B. IPv6 roadmaps of network equipment vendors b. Cisco ======================== Simon Pollard (SP) presented Ciscos Roadmap for IPv6. Gert Doering (GD): The IOS upgrade is not really free available - you need to buy the IP+ option package before you can make the upgrade. SP: This is true for the low-end platforms - but most people have IP+ anyway PVP: What about filtering and OSPF6. SP: Available - a beta of OSPFv3 will be out in October 2002. ?: What about Layer3 Switches? SP: They will come in Q3/2002 ?: Will there be a Ciso-PIX for IPv6? SP: This is planned for Q1/2003 ?: Is there 6PE and NAT/PAT for v6? SP: Yes, we have this for the PE-routers GD: IOS has become very large - you can't fit it into the small routers without upgrading Flash and Memory. Customers are not willing to spend money in order to upgrade. Make IOS smaller. An Image-size of 4MB would be good. SP: Customers will pay for the router-upgrade if they see the business drive of IPv6. However, Cisco is working on re-packaged IOS for the lower platforms. The memory-footprint will probably be 8 MB. GD: 4MB should be the target. ======================== C. Global IPv6 routing table status ======================== Gert Doerings presentation is available at: http://www.space.net/~gert/RIPE/R42-v6-table/ Conclusions: - Downstream filtering recommended - You should watch the announcements of your peers. PVP: 6bone has changed it's policy to give out /32 now, four of these prefixes should be visible. 15 are in the table. ?: Is there a canonical filter-list for IPv6 ? GD: Not yet. ?: Would you be up to maintain such a list? GD: I will discuss this with David Kessens and we should move the discussion on this topic to the mailing-list. === COFFEE BREAK 10:35 - 10:50 === ?: Is it easy to filter unassigned ASNs ? GD: Technically this is possible but it's preferable to talk to the people that are making the mistakes. ======================== D. Tunnelbrokers & ipv6 in practice ======================== Pim van Pelts presentation is available at: http://www.ripe.net/ripe/meetings/archive/ripe-42/presentations/ ripe42-ipv6-ipng/ PVP: Sixxs, a IPv6 tunnel-broker for LIRs in the RIPE-region is looking for participants that are willing to be a POP for this service. ?: What about the 6-to-4 tunnels? PVP: At the time we started, static tunneling was the only thing available. Today, if you run a 6-to-4 relay, it's easy for everyone to join, so it's also easy for everyone to abuse the service. If you host the relay, you also have to filter the incoming IPv4 traffic which is not easy. Attacks by script-kiddies on the next-hop of the relay (which is IPv4) are common today. DK: There have also been native V6-DoS-attacks, it's really scary. ======================== E. IPv6 Promotion Council Activities Overview ======================== Kosuke Ito's presentated an overview of the activities of ipv6 promotion council in Japan. More information about the council can be found at: http://www.v6pc.jp/index_e.html - The audience had no questions or comments. ======================== F. IPv6 capable RR DNS servers - what is needed, what are the issues ?!? ======================== DK: IPv6 capable RR DNS Servers should be discussed in the LIR-WG. - the audience agreed ======================== G. IPv6 RR DNS - is it ip6.int or ip6.arpa? Why? Documented where? ======================== Joao Luis Silva Damas presentation is available at: http://www.ripe.net/ripe/meetings/archive/ripe-42/presentations/ ripe42-ipv6-dns/ The recommendation is to populate ip6.arpa and phase out ip6.int - but what is wanted and how shall we proceed? ?: Software currently relies on ip6.int - you can't just switch it off. ?: Can't we just duplicate the delegation-records? GD: A good solution would be a CNAME very high in the hierarchy DK: Can't we just do automatic delegation in both domains? Joao: ip6.int should be abandoned soon - if we duplicate it will not go away. GD: But older machines all use ip6.int. Joao: OK, for the time being both delegations are possible. But should it be done automatically or do we only delegate in ip6.int if someone really wants it? GD: RIPE NCC should investigate if it's possible to do away with ip6.int and make a solution with CNAMEs. Make some experiments and report at RIPE 43 ACTION on RIPE NCC: Investigate the CNAME and other solutions for v6-reverse delegation. Wilfried Woeber: Automatic delegation for ip6.int and ip6.arpa appears the best solution, but if someone requests different delegations in ip6.arpa and ip6.int, RIPE NCC should not prevent this. Mohsen Suissi: RIPE NCC did this in the past, at least for 2002:0660::/35 both delegations were made. DNS reverse delegation must not be done at the parent zone before making sure the children (master & slaves) are ready. DK: RIPE NCC, could you investigate the possibilities for automatic delegation? Joao: OK, we will do the automatic delegation in both trees by default and we will allow different configuration if the user wants it. ?: But would this approach not lead to inconsistent data in the two domains? DK: It's only reverse delegation, that should have no big impact. DK: OK, 6-to-4 reverse delegation will also happen in ip6.arpa. What about this? Joao: The draft on 6 to 4 DNS (draft-ietf-ngtrans-6to4-dns-00.txt) is not very specific. RIRs will do the delegation based on the IPv4 /8s that they are authoritative for, but anything else is not clear yet. DK: What about the 6bone addresses and ip6.arpa Joao: I am not familiar with that. DK: Could you investigate this and give a more specific presentation at RIPE43? Joao: Sure. ACTION on RIPE NCC: Give an overview of 6-to-4 reverse delegation issues at RIPE 43 ======================== H. lbnamed Bug Discussion ======================== Francis Dupont explained that an updated version of lbnamed is available and urged everyone using lbnamed to update to the latest version. ======================== I. IPv6 allocation survey ======================== Mirjam Kuehne announced that the survey will be published on the web. The presentation was not given in this session due to shortage of time. The survey is available at: http://www.ripe.net/ripe/meetings/archive/ripe-42/presentations/ ripe42-ipv6-survey/ ======================== J. Euro6IX and layer 3 IX addressing ======================== Raffaele D'Albenzio's presentation is available at: http://www.euro6ix.org/ingles/Presentations/ 020430-TILAB-DalbenzioGuardini-RIPEPresentation.pdf - The audience had no questions or comments. == DK reminded that there is not much time left. The time for each of the following presentations was restricted to less than 5 minutes. == ======================== K. Developments/initiatives regarding IPv6 in the RIPE region and beyond The Hungarian Tipster6 project ======================== Geza Turchanyi gave a short overview on the tipster6-project and provided some statistics on the v6-capability of several unix-distributions. (Sun, BSD, Linux) Geza's presentation is available at: http://www.ripe.net/ripe/meetings/archive/ripe-42/presentations/ ripe42-ipv6-tipster6/index.html ======================== K. Developments/initiatives regarding IPv6 in the RIPE region and beyond French NIC initiative regarding DNSv6 deployment ======================== Mohsen Suissi presentation is available at: http://www.ripe.net/ripe/meetings/archive/ripe-42/presentations/ ripe42-ipv6-souissi.pdf Mohsen Suissi pointed out that currently not many TLD-Nameservers are native v6-speakers. AFNIC is willing to help other NICs to roll out v6 DNS. AFNIC also applied to become secondary for ip6.arpa. The request was submitted to IANA but nothing happened so far. ======================== L. LIR-WG session on IPv6 policy ======================== The iproposal for a global interim IPv6 Allocation Policy was accepted by the LIR-WG. ======================== Z. AOB ======================== Nothing reported ======================== Summary of actions arising from this meeting ======================== 42.1 ACTION on RIPE NCC: Investigate the CNAME and other solutions for v6-reverse delegation. 42.2 ACTION on RIPE NCC: Give an overview of 6-to-4 reverse delegation issues at RIPE 43 ------------------------------------------------------------------------
