Survey on Internet Traffic Engineering practices.
by Kévin Vermeulen 20 Sep '24

20 Sep '24

Hey Nanog, We are a group of researchers from LAAS-CNRS and UCLouvain. We are currently conducting a research study on inter-domain traffic engineering practices and their impact on the internet. We are reaching out to network operators to gather insights on practical implementations of inter-domain traffic engineering. Specifically, we are interested in understanding the timeframes and prefixes involved in traffic engineering efforts. If you have conducted inter-domain traffic engineering, could you kindly provide information about your traffic engineering practices. You can do so via our survey form https://forms.gle/2B6hW5Rs98rjiLLN7. Your participation would greatly contribute to our understanding of current practices and trends in network traffic engineering. We assure you that any information shared will be treated with strict confidentiality and used solely for research purposes. Any findings that will be published will be anonymized. For any questions please let us know. Best regards, Omar Darwich, Kevin Vermeulen, Cristel Pelsser

Cloudflare's rpki.json file is missing IPv4 ROAs longer than /24
by Steven Wallace 18 Sep '24

18 Sep '24

Greeting, Internet2 uses Cloudflare’s https://rpki.cloudflare.com/rpki.json as an alternate source for RPKI-ROA information. We recently discovered that this file omits IPv4 ROAs longer than /24. It would be helpful if it included all ROAs. Interestingly, Cloudflare’s web-based validator does include longer ROAs: https://rpki.cloudflare.com/?view=validator&validateRoute=1351_209.198.99.6… Cloudflare, any chance you could include all ROAs in this file? thanks, steve Steven Wallace Director - Routing Integrity Internet2 ssw(a)internet2.edu

RFC 9234 route leak prevention in the wild!
by Job Snijders 18 Sep '24

18 Sep '24

Dear all, I'd like to share an update on RFC 9234 deployment. RFC 9234 titled "BGP Open Policy" aka the "Only-To-Customer" (OTC) BGP Path Attribute is an anti-route-leak mechanism which is *NOT* based on RPKI! (yes ... routing security is more than just RPKI! :-) The basic idea of 9234 is that BGP routers (based on their role in the Gao-Rexford inter-domain routing model) attach a special BGP Path attribute, or take action based on the presence and contents of this BGP Path attribute - with the intention to constrain a route's propagation radius to just the downstream customer cone of the neighboring ASN. Most operators will intuitively understand that any route propagating through multiple IX route servers operated by different IXPs is a route leak: ``` IXP_1 IXP_2 / \ / \ / \ / \ ISP_A ISP_B ISP_C (receives) (leaker) (originates) ``` (figure 1. propagation from right to left; leak scenario) In the above example, ISP_A originates a route towards IXP_1's route servers, IXP_1 propagates the route to ISP_B (so far so good); but for one reason or another ISP_B subsequently continues propagation of the route towards IXP_2's route servers, who in turn propagate it to ISP_C. ISP_B is forwarding IP traffic between ISP_A and ISP_C for zero revenue. ISP_A and ISP_C are probably not expecting ISP_B to be in the middle. This situation can happen as a result of a misconfiguration in ISP_B's equipment, even when all participants use IRR & RPKI ROV to attempt to mitigate the worst routing incidents. What does it matter / impact ============================ Calgary-based YYCIX deployed RFC9234 support in late 2022/early 2023 using OpenBGPD; and FranceIX deployed support using BIRD in Q2 2024. Both IXPs configured their route servers to reject BGP routes that have an OTC attribute attached, and to attach an OTC attribute when propagating routes to the Route Server's peers. As it happens to be, currently (Mon Sep 2 12:26:50 UTC 2024) a small route leak is happening involving both YYCIX and FranceIX Route Servers via an ISP connected to both IXP's Route Servers; with the leak being stopped at YYCIX thanks to RFC 9234! Appendix A contains a table of leaked IPv4 routes. Let's zoom in on 1 entry: ``` $ bgpctl show rib 157.185.154.0/24 detail BGP routing table entry for 157.185.154.0/24 6939 38040 54994 Nexthop 206.126.225.20 (via 206.126.225.20) Neighbor 206.126.225.20 (216.218.252.194) Origin IGP, metric 1911, localpref 100, weight 0, ovs not-found, avs unknown, external, otc leak Last update: 11:58:08 ago Communities: 0:2906 0:16265 0:16276 0:18638 0:41690 0:48641 0:49029 Ext. Communities: ovs not-found Large Communities: 53339:11:1 53339:11:3 Aggregator: 54994 [163.171.131.254] OTC: 51706 ``` (figure 2. inspecting an leaked route using OpenBGPD's CLI) In figure 2. one can see the route is marked as 'otc leak', this was made possible because FranceIX's route server's attached the OTC attribute with the ASN value set to their Route Server's ASN (51706). ``` YYCIX FranceIX . x <adds OTC> \ . \ / \ ISP_A 6939_38040 54994 ``` (figure 3. right to left: real world example of blocked leak) In figure 3 AS 54994 originates 157.185.154.0/24 and propagates a route towards the FranceIX route servers. FranceIX accepts this route (probably because an IRR route object exists) and propagates it onward with the "Only-To-Customer" attribute set to 51706. The route is received by AS 38040, who appear to propagate the route to their upstream 6939. << An AS 38040 router is likely misconfigured! >> Then 6939 sends its customer's routes to the YYCIX route server, but the YYCIX route server recognizes that the route already passed through a 'valley' and thus considers this a leak; and blocks further propagation towards ISP_A. Impact with partial deployment ============================== RFC 9234 is an easy mechanism to configure and debug for both small & large network operators and IXP route server operators. In the above scenario YYCIX and FranceIX are likely the only 2 entities in the entire AS path which support RFC 9234; but we're already seeing leaks being blocked despite partial deployment! It's not hard to imagine that many IX-to-IX route leaks can be blocked with only the IXP operators themselves enabling RFC 9234 support. The world's most populair RS implementations (BIRD and OpenBGPD) already support RFC 9234! Tens of thousands of IX customers would enjoy the benefits of a few hundred IXPs taking action. RFC 9234 has no dependency on the RPKI, this means tha What can you do? ================ Just ask your vendors (your hardware routers and IXPs) to implement and deploy RFC 9234! :-) The more people ask, the more it'll bubble to the top of the priority list. The cost of implementing & deploying RFC 9234 is excellent bang for buck. Closing words ============= Shout out to our friends at FranceIX and MSK-IX for being amongst the first IXPs to deploy RFC 9234! Your effort helped reduce the potential impact of today's route leak!

Third Party VoIP Over Xfinity
by Matt Hoppes 14 Sep '24

14 Sep '24

I have an employee who has recently switched to Xfinity cable service. Ever since they switched their internet service their work phones will not stay registered for more than about 3 minutes. These same phones have been used on many ISPs without issues. The same config has been used behind multiple levels of NAT without issues. She was fine, until she switched to XFinity. Of course, XFinity support is absolutely worthless. Anyone from XFinity Tier 3 or such that might be able to offer assistance? I suspect it's something stupid with either NAT overload in the modem or the modem not keeping the SIP channels open. I've tried playing around with registration times without any success. And again, we've never had issues with these phones or this setup with any other ISP.
