Large BGP Communities in IETF
by Job Snijders 06 Sep '16

06 Sep '16

Beste NLNOGers, BGP Communities zoals gedefinieerd in RFC 1997 zijn de meest gangbare manier om meta-informatie uit te wisselen tussen ASNs zoals "prepend hier", "krik de local pref omhoog", etc. BGP Communities zoals beschreven in RFC1997 zijn 32 bits lang. De conventie is dat de eerste 16 bits het AS nummer zijn waarin de laatste 16 bits relevantie hebben. Met de introductie van 4-byte ASNs, heeft de IETF helaas de plank niet helemaal raak geslagen: je kan geen 32 bit waarde kwijt in een veld van 16 bits lang. Het gebrek aan wijdverspreid ondersteunde BGP Communities voor 4-byte ASNs leid tot allerlei gekloot: operators met een 4-byte ASN gebruiken bijvoorbeeld een private 16 bit ASN en verliezen daarmee globale uniekheid van hun communities, of ze gaan terug naar RIPE NCC en zeggen "doe toch maar een ouderwetse 16 bit-er" en hebben vervolgens te maken met het AS omnummer werk. De IETF IDR working group beheert de BGP specificatie, en dit is waar een groep operators het voor elkaar probeert te boxen om een simpele, grotere BGP community te standardiseren om het operationele beheer van netwerken met een 4-byte ASN makkelijker te maken. Het voorstel dat nu op tafel ligt heet "Large BGP Communities" - in essentie is het een community van 12 bytes, waarbij de eerste 4 bytes het ASN zijn, en de laatste 8 bytes vrij in te vullen zijn door de operator. Zo kun je ongeacht of je een 2 of 4-byte ASN hebt, 8 bytes besteden aan netwerk acties, en 8 bytes laat zelfs genoeg ruimte om een target 4-byte ASN en een 'actie' identifier. Mijn verzoek aan de IDR kun je hier lezen: https://mailarchive.ietf.org/arch/msg/idr/vEa3744YRl5Sj8bUB_I54Uay-fE En ik heb jullie hulp nodig... want als operators zich niet laten horen, zal er niets veranderen, en blijft het probleem voort etteren. De IETF is bijzonder goed in bikeshedden en academische ideeen produceren, maar het is nu tijd om de handen in een te slaan en een oplossing te eisen. Hoe kunnen jullie helpen? ------------------------- 1) Lees je in: http://largebgpcommunities.net/ bevat veel informatie over wat Large BGP Communities zijn 2) Betuig je steun in publiek op de plek waar het er toe doet: email de IDR mailing list met iets ala "I support adoption of this draft". Je kan dat als volgt doen: stap 1: subscribe jezelf op https://www.ietf.org/mailman/listinfo/idr stap 2, email the IDR iets in de geest van: From: $JOU To: idr(a)ietf.org Subject: Re: [Idr] Request to adopt draft-heitz-idr-large-community Job Snijders wrote: > I would like to request that the IDR Working Group adopts > draft-heitz-idr-large-community [1] as a working group document. I support this Regards, $JIJ ------------------------- Met vriendelijke groeten, Job

Last call for presentations and Draft programme for RIPE 73
by Benno Overeinder 06 Sep '16

06 Sep '16

Colleagues, A list of currently accepted RIPE 73 presentations is now published at: https://ripe73.ripe.net/programme/meeting-plan/draft-programme/ There are still few slots remaining for a final RIPE 73 programme and RIPE Programme Committee will accept new proposals until 25 September 2016. This is our last call for you to submit your proposals. You can find the CFP for RIPE 73 below, or at https://ripe73.ripe.net/submit-topic/cfp/, for your proposals for plenary session presentations, tutorials, workshops, BoFs (Birds of a Feather sessions) and lightning talks. Please also note that speakers do not receive any extra reduction or funding towards the meeting fee at the RIPE Meetings. Kind regards, Benno Overeinder RIPE PC Chair https://www.ripe.net/participate/meetings/ripe-meetings/pc -------------------->>><<<-------------------- Call for Presentations A RIPE Meeting is an open event where Internet Service Providers, network operators and other interested parties get together. Although the meeting is mostly technical, it is also a chance for people to meet and network with others in their field. RIPE 73 will take place from 24-28 October 2016 in Madrid, Spain. The RIPE Programme Committee (PC) is now seeking content proposals from the RIPE community for the plenary sessions, BoFs (Birds of a Feather sessions), panels, workshops, tutorials and lightning talks at RIPE 73. See the full descriptions of the different presentation formats, https://ripe73.ripe.net/submit-topic/presentation-formats/. Proposals for plenary sessions, BoFs, panels, workshops and tutorials must be submitted for full consideration no later than 25 September 2016. Proposals submitted after this date will be considered depending on the remaining available space in the programme. The PC is looking for presentations covering topics of network engineering and operations, including but not limited to: - IPv6 deployment - Managing IPv4 scarcity in operations - Commercial transactions of IPv4 addresses - Data centre technologies - Network and DNS operations - Internet governance and regulatory practices - Network and routing security - Content delivery - Internet peering and mobile data exchange - Internet of Things (IoT) Submissions RIPE Meeting attendees are quite sensitive to keeping presentations non-commercial, and product marketing talks are strongly discouraged. Repeated audience feedback shows that the most successful talks focus on operational experience, research results, or case studies. For example, presenters wishing to describe a commercial solution should focus on the underlying technology and not attempt a product demonstration. Presenters should indicate how much time they will require. In general, the time allocated for the different presentation formats is as follows: - Plenary presentations: 20-25 minutes presentation with 5-10 minutes discussion - Tutorials: up to two hours (Monday morning) - Workshops: one hour (during evening sessions) to two hours (Monday morning) - BoFs: approximately one hour - Lightning talks: 10 minutes The following general requirements apply: - Proposals must be submitted using the meeting submission system, https://ripe73.ripe.net/submit-topic/submission-form/. - Lightning talks should also be submitted using the meeting submission system (https://ripe73.ripe.net/submit-topic/submission-form/) and can be submitted any time up to and including the meeting week. The allocation of lightning talks will be announced on short notice---in some cases on the same day but often one day prior to the time slot allocated. - Presenters who propose a panel or BoF are encouraged to include speakers from several (perhaps even competing) companies and/or a neutral facilitator. - All presentation proposals will only be considered by the PC if they contain at least draft presentation slides (slides may be updated later on). For panels, proposals must contain a clear description, as well as the names of invited panellists, presenters and moderators. - Due to potential technical issues, presenters/panellists should be physically present at the RIPE Meeting.

Negeer route announcements met Bogon ASNs in het AS_PATH attribuut
by Job Snijders 03 Jun '16

03 Jun '16

Hi NLNOG, Onder het mom van "make routing tables great again!" wil ik iedereen aanmoedigen route announcements waarvan het AS_PATH attribuut een Bogon ASN bevat weg te filteren. Hier een aantal up-to-date voorbeelden op basis van RFC 4893, RFC 5398 en RFC 6996. De redenatie is als volgt: 1/ Op het publieke internet, hebben Private ASNs geen plek. 2/ Wanneer jouw apparatuur 4-byte ASNs support, dan zou je nooit _23456_ in een AS_PATH moeten zien, maar altijd in plaats daarvan het originele 4-byte ASN. Zie je toch _23456_ in een pad, dan is dit een grove misconfiguratie aan de andere kant, een "bgp-optimizer"-achtig-iets dat geen 4-byte ASNs snapt of andere gekkigheid. Zaken die we niet moeten aanmoedigen door zulke routes te accepteren. Bij mijn werkgever mikken we er op om dit in juli 2016 uit te rollen. Hieronder voorbeeld configuraties voor diverse platformen. Met vriendelijke groeten, Job ---------------------------- Juniper: policy-options { as-path-group bogon-asns { /* RFC 4893 AS_TRANS */ as-path as_trans ".* 23456 .*"; /* RFC 5398 and Reserved ASNs */ as-path reserved1 ".* [64496-131071] .*"; /* RFC 6996 */ as-path reserved2 ".* [4200000000-4294967295] .*"; } policy-statement import_from_ebgp { term bogon-asns { from as-path-group bogon-asns; then reject; } term ..... } } Cisco IOS XR: as-path-set bogon-asns passes-through '23456', passes-through '[64496..131071]', passes-through '[4200000000..4294967295]' end-set route-policy import_from_ebgp if as-path in bogon-asns then drop else ...... endif end-policy BIRD: define BOGON_ASNS = [23456, 64496..131071, 4200000000..4294967295]; function ebgp_import() int set bogon_asns; { # ignore bogon AS_PATHs bogon_asns = BOGON_ASNS; if ( bgp_path ~ bogon_asns ) then { print "Reject: bogon AS_PATH: ", net, " ", bgp_path; reject; } ....... }
