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 feature: Comparing certified resources to BGP routing
by Alex Band 24 Aug '11

24 Aug '11

[Apologies for duplicate e-mails] Dear Colleagues, The power of the Resource Certification system lies within the fact that you can always be sure that a valid Route Origin Authorisation (ROA), stating which Autonomous System (AS) is authorised to originate a certain prefix, can only be created by the legitimate holder of the address space. In addition, our aim to make the data set as complete and well maintained as possible. To make it easier for our members using the service to achieve this, we have just released a new feature in the Resource Certification Service that compares the certified resources an LIR holds and the ROAs they have created with the BGP announcements seen by the RIPE NCC Remote Route Collectors. It will display the validation results, and can notify the user of mismatches and potential hijacking attempts. To learn more about it, please refer to this article on RIPE Labs: https://labs.ripe.net/Members/AlexBand/matching-roas-to-bgp-routing We look forward to hearing about your experiences using the first iteration of this feature, so we can work on refining it. Kind regards, Alex Band Product Manager RIPE NCC
