In Dublin's fair city, where the routes are so pretty.
by Rob Evans 06 Feb '13

06 Feb '13

The time is fast approaching where the good people of the NCC start to chivvy the working groups chairs into submitting their agenda points for the next meeting. Which means, of course, that the working groups chairs are going to chivvy the working group members into suggesting agenda points for the next meeting. This is that message. On the provisional agenda our meeting will be after lunch on Thursday, so if you have some suggestions of what you'd like to see discussed, or would like to present something, please either drop a message to Joao and myself at <routing-wg-chairs(a)ripe.net> or send it to the list. Provisional meeting plan: <https://ripe66.ripe.net/programme/meeting-plan/> Registration: <https://ripe66.ripe.net/attend/register/> I hope to see you all in Dublin! Cheers, Rob

BGP Origin Validation State Extended Community
by Matjaž Straus Istenič 05 Feb '13

05 Feb '13

Hi, group, somebody familiar with the well-known BGP communities for route origin validation? From the current draft-ietf-sidr-origin-validation-signaling I can see that IANA has to assign a new value from the non-transitive range of the "BGP Opaque Extended Community" type registry for the purpose. It is interesting that Juniper documentation has already invented the "origin-validation-state-(valid|invalid|unknown)" well-known communities. They are just on the paper though, at least in Junos OS 12.2. Kind regards, Matjaž
