Route object creation authorization
by Havard Eidnes 16 Apr '19

16 Apr '19

Hi, it looks like "things happened while I wasn't watching"... I've just had a run-in with the route object authorization rules as presently implemented in the RIPE database. I found the following flow chart documenting the authorization procedure: https://www.ripe.net/support/training/material/Routing-Security-Training-Co… which is referenced from https://www.ripe.net/manage-ips-and-asns/db/support/managing-route-objects-… The question I have is this: What is the policy reason for having a pre-existing route object play any role in authenticating the creation of a new route object, so that it in effect overrides any mnt-routes: fields of the corresponding inetnum object for the address space holder? When a customer who has his own address space and controls his own inetnum object, but lets his current ISP originate the route with the ISP's ASN as origin, but wants to move to another ISP, given the current rules, the current ISP is able to hold the customer hostage by refusing to create a new route object with a different ASN as origin. I would not have thought it was RIPE's role to raise and enforce such a barrier? I also can't quite comprehend why a route object would need the "mnt-routes" or "mnt-lower" attributes -- in an inetnum object I can understand the semantics of those, but in a route? Best regards, - Håvard

RPKI Validator 3: RIS dump downloads - still plain HTTP
by nusenu 13 Mar '19

13 Mar '19

Hi, back in September I opened an issue on github [1] about RPKI Validator 3 fetching RIS dumps via plain HTTP connections, two weeks ago the issue got closed. First I was glad since I assumed the issue got closed because it is fixed but then I noticed that the issue still persists in rpki-validator-3.0-377 so I'm wondering why the issue got closed? thanks, nusenu [1] https://github.com/RIPE-NCC/rpki-validator-3/issues/50 -- https://twitter.com/nusenu_ https://mastodon.social/@nusenu

New on RIPE Labs: RIS Live BGP Message Stream
by Mirjam Kuehne 26 Feb '19

26 Feb '19

Dear colleagues, We are launching a prototype called RIS Live, a feed that offers BGP messages in real time. It collects information from the RIS Route Collectors (RRCs) and uses a WebSocket JSON API to monitor and detect routing events around the world. Please find more details on RIPE Labs: https://labs.ripe.net/Members/chris_amin/ris-live-bgp-message-stream Kind regards, Mirjam Kühne RIPE NCC

Analysing traffic in context of rejecting RPKI invalids using pmacct
by Job Snijders 13 Feb '19

13 Feb '19

Dear all, Whether to deploy RPKI Origin Validation with an "invalid == reject" policy really is a business decision. One has to weigh the pros and cons: what are the direct and indirect costs of accepting misconfigurations or hijacks for my company? what is the cost of deploying RPKI? What is the cost of honoring misconfigured RPKI ROAs? There are a few thousand misconfigured ROAs, what does this mean for me? To answer these questions, Paolo Lucente and myself worked to extend pmacct traffic analysis engine (http://pmacct.net/) in such a way that it can do perform the RFC 6811 Origin Validation procedure and present the outcome as a property in the flow aggregation process. Pmacct has the ability to ingest BGP feeds and correlate the BGP data to the sflow/netflow/ipfix data. This allows for fantastic business intelligence, you can see exactly how much traffic is flowing from what customers to what endpoints for what reason! Pmacct implemented Origin Validation in a cute way: it separates out RPKI invalid BGP announcements into two categories: a) "invalid with no overlapping or alternative route" (aka will be blackholed if 'invalid == reject') b) "invalid but an overlapping unknown/valid announcement also exists" (end-to-end connectivity can still work). Because pmacct separates out the various types kinds of (invalid) BGP announcements, operators don't have to do deploy *anything* in their network to get a good grasp on how their connectivity to the rest of the Internet would look like after deploying a "invalid == reject" policy. No changes to your network configurations are required to make use of this feature, you don't need to tag routes with communities or do other tricks. All the analysis happens inside pmacct. Of course we tested this first in the NTT global backbone AS 2914! At the moment of writing, we're seeing less than a handful of gigabits per second being send towards BGP announcements that are RPKI Invalid and for which no alternative route exists. In context of NTT's backbone that amount of traffic is just statistical noise. This is a very encouraging sign, it may help us move towards the goal of deploying RPKI Origin Validation in AS 2914. Nusenu wrote a great blog post on where these RPKI ROA misconfigurations are located, i recommend reading their posts to develop a better understanding of the problem space: https://medium.com/@nusenu/where-are-rpki-unreachable-networks-located-65c7… Even if you don't intend to deploy RPKI Origin Validation (or are single-homed), pmacct's RPKI capabilities can be useful in forensic investigations. It'll be easier to analyse how much and what kind of traffic for what period of time was sent to a possible hijack. This will help you when writing RFOs! If you want to testdrive this feature, fetch pmacct version 1.7.3-rc1 from https://github.com/pmacct/pmacct/releases/tag/1.7.3-rc1 Documentation on how to configure the feature: https://github.com/pmacct/pmacct/blob/master/QUICKSTART#L1783-#L1833 https://github.com/pmacct/pmacct/blob/master/CONFIG-KEYS#L2626-#L2647 Let us know what you think! Or if you'd like to chat telemetry with Paolo or me about analysing the effects of BGP hijacks and RPKI, we'll both be at the San Francisco NANOG meeting next week! Kind regards, Job
