For your information, we are producing a SLURM file as part of our implementation. This is noted in the slides. Purely as an informational and with no intent to otherwise engage in your policy proposal process, It has been my intention to bring our implementation report to the RIPE meeting in Berlin and present it in the routing WG. Please let me know if this would be useful or interesting, or is not helpful. -George On Fri, Feb 21, 2020 at 2:54 PM Job Snijders <job at ntt.net> wrote: > > Dear working group, > > On Thu, Feb 20, 2020 at 04:39:26PM +0200, Petrit Hasani wrote: > > The goal of the proposal is to ask the RIPE NCC to create ROAs with > > origin AS0 for all unallocated and unassigned address space under its > > control. > > > > The proposal has been updated following the last round of discussion. > > Version 2 of the proposal includes a specification for the RIPE NCC to > > create all AS0 ROAs under a specific Trust Anchor. > > > > The RIPE NCC has prepared an impact analysis on this latest proposal > > version to support the community’s discussion. > > > > You can find the proposal and impact analysis at: > > https://www.ripe.net/participate/policies/proposals/2019-08 > > https://www.ripe.net/participate/policies/proposals/2019-08#impact-analysis > > I oppose the policy proposal.
