RPKI Route Origin Validation and AS3333
by Nathalie Trenaman 21 Mar '21

21 Mar '21

Dear Colleagues, Working Group, As discussed previously in this mailing list, some community members expressed that they would like to see the RIPE NCC perform Route Origin Validation on AS3333. We decided to ask the community for advice and guidance on how we should proceed. What is Route Origin Validation? Route Origin Validation is a mechanism by which route advertisements can be authenticated as originating from an expected autonomous system (AS). The best current practice is to drop RPKI invalid BGP announcements. These are announcements that conflict with the statement as described in a Route Origin Authorization (ROA). What is AS3333? This is the AS Number for the RIPE NCC’s main service network. It includes most of our *.ripe.net <http://ripe.net/> websites, including the LIR Portal (my.ripe.net <http://my.ripe.net/>) and the RIPE Database. What is the Problem? Currently, some of our upstream providers already perform ROV. This means that some of our members that potentially misconfigured their ROA or members who have lost control of creation and modification of their ROAs cannot reach our services via those peers. On the other hand, some of our upstream providers do not perform ROV, and if a member’s prefix is being announced by a hijacker, they cannot access our services. We already received a report about this.This is also not an ideal situation. From the network operations perspective, there are no obstacles to enable ROV on AS3333, however, we have to consider that members or End Users who announce something different in BGP than their ROA claims, will be dropped and lose access to our services from their network. This includes the RPKI Dashboard where they can make changes to their ROAs. This is specially relevant when members operate certificate generation in hosted mode which is the current operation mode for almost all for our members. From an analysis we made on 10 February, there were 511 of such announcements from our members and End Users. Our current RPKI Terms and Conditions do not mention that a Member or End User ROA should match their routing intentions, or any implications it may have if the ROA does not match their BGP announcement. If the community decides it is important that AS3333 performs ROV, our legal team needs to update the RPKI Terms and Conditions to reflect the potential impact. I welcome a respectful discussion and look forward to your advice and guidance. Kind regards, Nathalie Trenaman Routing Security Programme Manager RIPE NCC

Call for Presentations - RIPE 82
by Peter Lothberg 20 Mar '21

20 Mar '21

Job, Are you saying that the routing WG does not do it's job as you are suggesting that "routing problems" might disrupt the presentations? I suggest that everyone go back to work and fix their networks for everyone benefit, or do we need o have "routing 101? I can redo one of the BGP4 talks from beginning of 1990's if we forgot it all.. Today, any (forwarding) disruption longer than 200ms is unacceptable. (Did you make sure your vendor did the right thing in their HW/SW?) -Peter > > We'll ask presenters to pre-recorded their talk to try to prevent local, > logistcal, and/or routing problems from impacting the meeting. :-) > > Kind regards, > > Job, Paul, Ignas > Routing Working Group Chairs

Join the RIPE NCC Open House: Hosted vs. Delegated RPKI
by Nathalie Trenaman 15 Mar '21

15 Mar '21

Dear colleagues, We’re hosting a RIPE NCC Open House this Friday, 19 March (09:00 UTC), on the differences between hosted and delegated RPKI, and their use cases. Alex Band, Director of Product Development for NLNetLabs and I will discuss different scenarios in which hosted and delegated RPKI could be useful, and will give a short demo on how to use Krill as a software solution. Event details and registration can be found at: https://www.ripe.net/participate/meetings/open-house/ripe-ncc-open-house-ho… <https://www.ripe.net/participate/meetings/open-house/ripe-ncc-open-house-ho…> Hope to see you there! Kind regards, Nathalie Trenaman RIPE NCC
