Implementation of NWI-5 out of region ROUTE(6) objects
by denis walker 12 Feb '18

12 Feb '18

Colleagues Based on the proposal by Tim for NWI-5 and the following discussions, the DB-WG co-chairs would like the RIPE NCC to schedule implementation of the following actions: -Remove the ASN authorisation requirement for ROUTE(6) object creation -Deprecate the "mnt-routes:" attribute in the AUT-NUM object -Remove the 'pending object creation' functionality for route creation -Create the source 'RIPE-NONAUTH' -Move all ROUTE(6) objects relating to non RIPE managed address space to this new source (pending eventual deletion after further discussion) -Move all non ripe managed AUT-NUM objects to this new source (pending eventual deletion after further discussion) -Adjust the query service as suggested in Tim's proposal -Disallow creation of any new AUT-NUM or ROUTE(6) objects in the RIPE Database for non RIPE managed resources, but allow existing objects to be modified or deleted -Remove the "mnt-routes:" attribute from all the placeholder INET(6)NUM objects in the RIPE Database for non RIPE managed address space -Delete the MNTNER object with the public password ('fixing' any other database objects that may refer to it) -Update all documentation to reflect the new processes -Ensure that the inter RIR transfer process for resources moving into the RIPE managed address space does not allow the transfer of ROUTE(6) objects from source RIPE-NONAUTH to source RIPE without the agreement of the resource holder cheersDenis & Williamco-chairs DB-WG

I don't think there is a good case to continue to allow the creation of new ROUTE(6) objects in the RIPE DB for non RIPE address space. I'm seeing quite some abuse of this 'feature', where spammers/hijackers register out-of-region prefixes to sneak them into people's prefix-list filters. It would be good if that hole can be plugged. Separately, a study should be done on how to deal with the existing non-RIPE-managed ROUTE(6) objects in the DB. Maybe some cleanup can be done for at least for a subset of those objects. Kind regards, Job

Comparison of open source switch software?
by Hank Nussbacher 06 Jan '18

I know this is *routing* WG but I figured I would try anyway. I have seen numerous comparisons and RIPE presentations on performance issues of BIRD vs Quagga vs FRR. I am looking for the same thing of switch software. Has anyone done a feature comparison between: http://openvswitch.org/ https://www.openswitch.net/ https://cumulusnetworks.com/products/cumulus-linux/ ...any other I am missing... And even better - has anyone done a benchmark to see which performs best? Thanks, Hank
