[routing-wg]Multihoming in IPv6 using PA space
by Iljitsch van Beijnum 28 Sep '06

28 Sep '06

[Going out to routing-wg and ipv6-wg, trim as needed in follow-ups] Before the last IETF meeting there was some discussion about the difficulties in multihoming using a prefix out of PA space from an ISP in IPv6. Because many ISPs filter at /32 or /35 in IPv6, the /48s (or /56s) used for multihoming are often filtered out. After some discussion with people from the IETF v6ops wg, I've written the draft mentioned below, outlining the problem and proposing a BGP community to tag the prefixes used for this so they can be un-filtered as needed. Feedback from people involved with and/or an interest in IPv6 routing is highly appreciated. I'd be happy to discuss the draft in either the routing or IPv6 wgs, or talk about it briefly at the end of my IPv6 routing tutorial on wednesday morning. And of course one-on-one in the hallway. The -01 with only minor changes should be up soon, or you can find it at http://www.muada.com/drafts/draft-van-beijnum-v6ops-pa-mhome- community-01.txt Begin forwarded message: > A New Internet-Draft is available from the on-line Internet-Drafts > directories. > Title : BGP Community for PA Multihoming > Author(s) : I. van Beijnum > Filename : draft-van-beijnum-v6ops-pa-mhome-community-00.txt > Pages : 8 > Date : 2006-9-11 > When an organization wants to connect to the internet using two or > more > Internet Service Providers (multihoming), this is usually done by > setting up BGP routing between the organization in question and > each of > its ISPs.

[routing-wg]Routing WG Charter revisited
by Joao Damas 20 Sep '06

20 Sep '06

All, The current charter of the RIPE routing working group is fairly narrow and outdated: http://www.ripe.net/ripe/wg/routing/index.html Specifically, "The group exchanges information about various Routing Registries. It is concerned with the growth of the routing tables on the Internet and started an effort to decrease their size in Europe." To start off your thought process here are a few points we believe the working group could think about - Evolution of the routing tables, for IPv4 and IPv6 - Dissemination of information on advances in routing (this is what most talks end up being about) - Work on BCP recommendations as appropriate to the current network - Discussion of interactions between RIR policies and procedures and Routing For the last point we are thinking about subjects like how is the new RIR CA project going to afffect ISPs, etc Opinions are most welcome. All the best Rob, Joao, Joachim

[routing-wg]DRAFT agenda for Routing WG Meeting at RIPE-53
by Rob Evans 18 Sep '06

18 Sep '06

Hi folks, Appended is the first draft of the agenda for the routing wg session at the upcoming RIPE meeting. There is still time available, so if you have anything to volunteer, now is as good a time as any. There's nothing about authorisation of route: object creation and modification as nobody has volunteered for that as yet. All the best, Rob Agenda, RIPE 53 Routing Working Group. Version 1. 17th September, 2006. A. Administrivia - Scribe - Agenda bashing. - Minutes of last meeting 5 minutes. Chairs. B. Recommendations on Route Aggregation 10 minutes. Philip Smith. C.

[routing-wg]RIPE 52 routing-wg minutes
by Joao Damas 18 Sep '06

18 Sep '06

With thanks to Arife Vural for taking the minutes, to my co-chair Rob Evans for making sure these got out there and to all who participated. See you soon at RIPE 53 or on the mailing lists. Joao Damas Routing-WG, Istanbul 2006 Chair: Joao Damas Date: 27 April, 2006 Afternoon Session - Previous minutes were approved. - Joao asked if there were any objections to Rob Evans being a co-chair of the WG. No objections were raised. - Philip Smith gave an update about Route Flap Damping obsoletion. http://www.ripe.net/ripe/meetings/ripe-52/presentations/ripe52- routing-deprecating-ripe-229.pdf The document, co-authored with Christian Panigl has been sent to the mailing list, but no comments have been received yet. Randy Bush: I read the document, liked it. I proposed vendors to change the implementation based on Geoff's presentation earlier this week. [http://www.ripe.net/ripe/meetings/ripe-52/presentations/ripe52- plenary-bgp-review.pdf] Gert Doering: I agree that the current way route-flap dampening is done is harmful. We should start work on a new recommendation how to get these extreme prefix noise dampened, but not 'normal' activity Joao: WG already has consensus, only thing is left whether the text reflects what we agreed. If so, let finish it. - Philip Smith talked about a Route Aggregation BCP He will have something to present next RIPE meeting about the recommendations. - Andrei Robachevsky gave an update about Authorization of "route:" objects in the DB. It's an update about the discussion that was in DB-WG last month. http://www.ripe.net/ripe/meetings/ripe-52/presentations/ripe52- routing-route-creation.pdf If the route-object holder change the provider, who will do the DB update? Ruediger: It's defined in RFC, and whois reflects that. Joao: We can change RFC and whois if it creates trouble. Ruediger Volk: Changing the procedure, I have not done the analysis of the consequences. Andrei Robachevsky: Need tweaking? Do we have to change paradigm? There is a work around, do best practice. Joao: Does anybody have any comments? I will summarize it, and to see the result. - David Ward gave a presentation about service peering and BGP for Inter-domain QoS Routing. [Slides weren't working during meeting, they are available at: http://www.ripe.net/ripe/meetings/ripe-52/presentations/ripe52- routing-bgp-qos-sicily.pdf] The proposal adds information on paths with varying QoS to inter-domain routing by adding it to BGP. Ruediger Volk: I'm not quite sure about the clarifications. This is for QoS for VPNS, does this apply IPv4? David Ward: Yes, it is. It is not tied to VPNs. Ruediger Volk: There is a scaling issue for BGP, did you take this into consideration while advertising same prefixes multiple times. David Ward: This is to be used between service sharing ISPs and not to be propagated globally through the Internet. Joao: Those messages are protocol specific? David Ward: Yes. - Ruediger presented some suggestions on how to proceed with Routing Security, IRR based authorization, Black-holing. Joao: Do you have a proposal on how to change the behaviour? Andrei: These data is available is the form of stats file. It does not tell the who is doing the authorization. Joao: Let's see what RIPE NCC can do about it. - Charter discussion: This was deferred due to lack of time at this meeting. - AOB There was no other business.
