by Rob Evans 02 Nov '11

02 Nov '11

All, With very many thanks to the RIPE NCC for their scribing skills, the draft minutes of our meeting in Amsterdam are now available for review: <http://www.ripe.net/ripe/groups/wg/routing/minutes/ripe-62> Please send comments to the list or <routing-wg-chairs(a)ripe.net>. Two matters arising from the meeting: 1 I would now like to start a four week "last call" on the routing recommendations draft so that it can be published as a RIPE document. Please send comments to the list. 2 It is an action on the chairmen of the working group to gather some interested parties in revising the document on Route Flap Dampening. All the best, Rob

New article on RIPE Labs: Addresses for RIPE RIS Beacons in Jeopardy
by Mirjam Kuehne 31 Oct '11

31 Oct '11

Dear colleagues, According to address policy, the experimental address allocations for RIPE RIS beacons have to be returned soon. This would mean we have to either discontinue the RIS beacons or request permanent allocations for them according to address policy. We are asking for community support to continue operating the RIS beacons at the current addresses and for support for the address allocations. Please read more on RIPE Labs: http://labs.ripe.net/Members/dfk/addresses-for-ripe-ris-beacons-in-jeoprady Kind Regards, Mirjam Kuehne RIPE NCC

128.0.0.0/16 configured as martian: Please update your routers
by Ingrid Wijte 27 Oct '11

27 Oct '11

[Apologies for duplicate emails] Dear colleagues, The RIPE NCC is aware that 128.0.0.0/16 is configured as a martian by default in (some) Juniper OS, even though RFC 5735 and RFC3330 outline that this /16 should no longer be reserved as specialised address space. We are exchanging the allocations that were already issued and for now we will (temporarily) stop using this specific /16. The RIPE NCC is working on this matter. For now, we urge everyone to change the default behaviour of their Juniper routers: set routing-options martians 128.0.0.0/16 orlonger allow set routing-options martians 191.255.0.0/16 orlonger allow set routing-options martians 223.255.255.0/24 exact allow Best regards, Ingrid Wijte Registration Services Assistant Manager RIPE NCC

Resource Certification/RPKI Workshop at RIPE 63
by Alex Band 13 Oct '11

13 Oct '11

RIPE 63 attendees interested in Resource Certification/RPKI are encouraged to take part in a workshop on Monday, 31 October from 9:30-12:30 in the Park Congress 2+3 rooms. ===================== What you'll learn ===================== The workshop will focus on BGP Origin Validation, based on the Resource Public Key Infrastructure (RPKI). You will learn how RPKI enables network operators to make more reliable routing decisions and how it protects against accidental mis-origination, the most common routing error we see today. Using various open-source tools from rpki.net and the RIPE NCC, you will be able to set up a resource certificate and create Route Origin Authorisation (ROA) objects, stating which Autonomous Systems are authorised to originate the prefixes you hold. After publishing your ROAs, you can validate them and configure routers to set routing preferences based on the RPKI status of your prefixes. This workshop will be a collaboration between Rob Austein, Randy Bush, Michael Elkins, Benno Overeinder (NLNet Labs), Jac Kloots (SURFnet), Cisco Systems, Juniper Networks and the RIPE NCC. ========================= Participation Details ========================= You do not need to register for this workshop. There are no prerequisites for using the rpki.net tools. In order to generate a certificate and configure ROAs on the RIPE NCC pilot server, you'll need to have an LIR Portal user account with access to the certification system or know the administrator credentials for your LIR Portal account. More information: http://ripe.net/certification/enable.html If you don't have an LIR Portal account or the necessary administrator credentials, you can still participate. We look forward to seeing you in Vienna! Kind regards, Alex Band Product Manager RIPE NCC
