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.
