I just want to mention that RPKI is officially supported on these Cisco platforms: ASR1000, 7600, ASR903 and ASR901 – releases are 15.2(1)S or XE 3.5. Early Field Trial is available for the following platforms (contact bduvivie at cisco dot com): ASR9000, CRS1, CRS3 and c12K (IOS-XR). Source (in French): http://reseauxblog.cisco.fr/2012/04/23/jai-teste-pour-vous-securiser-le-rou… The RIPE NCC also just released RPKI Validator 2.1.0 with some new features and improvements: https://www.ripe.net/certification/tools-and-resources Here are instructions on how to hook up our Validator toolset to one of the Ciscos above: https://www.ripe.net/certification/router-configuration Cheers, Alex Band RIPE NCC

IRRToolSetNG BoF slides and mailing list
by Benno Overeinder 19 Apr '12

19 Apr '12

Hello, After the IRRToolSetNG BoF on Monday, we announced that we will set up an email list for discussion on these issues. The email list is routing-tools(a)NLnetLabs.nl, and as the mailing list name suggests the topic is not exclusively IRRToolSet but rather generic router toolset issues for configuration, administration, maintenance, etc. Apart from the IRR/RPSL topics, discussions can certainly include new technologies like RPKI. The slide sets presented at the BoF will be made available in the RIPE 64 archives, https://ripe64.ripe.net/archives/ You can subscribe to the email list http://open.nlnetlabs.nl/mailman/listinfo/routing-tools Benno Overeinder Shane Kerr -- Benno J.
