new tool to reveal RE routing topology
by Steven Wallace 01 May '26

01 May '26

Greetings, Internet2 and CAIDA have released several ROOTBEER tools to help the global Research and Education community better understand routing policy across the R&E ecosystem. The tools are available here: https://rootbeer.internet2.edu One of the tools, the R&E Topology Report, depicts the routing topology visible from networks that peer with Internet2, AS11537. It is built from the full set of routes Internet2 receives across its peering sessions, including routes that are not selected as best paths. This gives the report a broader view than a conventional forwarding-path or best-path-only analysis. The report also includes routes rejected by Internet2’s routing policy, including routes rejected because they are RPKI Invalid, have an AS path containing a peer-lock AS, exceed prefix-length limits, or fail other policy checks. This pre-policy view is especially useful because it shows not only the routes Internet2 uses, but also the routes Internet2 sees and rejects. Below are several examples of insights the report can provide. We would like to extend this detailed pre-policy view to other R&E networks. During TNC26, we will hold the BoF “Coordinating BGP Policy and Tooling Across the Global R&E Infrastructure” on Thursday, 9:00–10:30 a.m. We will demonstrate progress on the ROOTBEER tools, invite input on future features, and discuss how data from other R&E networks could be incorporated to improve coverage and utility across the community. After TNC26, we will organize a follow-up meeting to review what we heard and provide an opportunity for those who could not attend TNC26 to share their input and discuss ways to expand the reach of these tools. Later today, I will also be demonstrating two ROOTBEER tools during ESnet’s CI Engineering Talk: 2pm ET. Steve Wallace from Internet2 will be talking about "Deep dive into two ROOTBEER tools, the Local Preference Probe and the R&E Global LPP report". The talks are always recorded. To join live you can use this link: https://ESnet.zoom.us/j/804696793 Here are some examples of what the RE Topology Report shows, with data from other networks; this can be expanded. steve Here’s a partial graph of how Internet2 received routes to ESnet. You can see it directly in the tool via: https://rootbeer.internet2.edu/re-topology-report/#asn=293 ![](cid:6FDCDF54-A161-4CD6-9003-F07C75A2AF71@mac.com "Screenshot 2026-05-01 at 11.07.44 AM.png") You select to see only the best path to see the paths Internet2 is using by selecting “Best paths only”. Details about each AS and its routes appear when you click on an AS. Here’s ESnet with best paths only selected: https://rootbeer.internet2.edu/re-topology-report/#asn=293&best=1 ![](cid:F3C181F4-D8AC-4AC3-8812-800CBF2BCE07@mac.com "Screenshot 2026-05-01 at 11.10.56 AM.png") A few others of interest: CERN https://rootbeer.internet2.edu/re-topology-report/#asn=513 ![](cid:E2DAA265-12B5-41EA-8D3A-E957AE549A8A@mac.com "Screenshot 2026-05-01 at 11.11.51 AM.png") SINET https://rootbeer.internet2.edu/re-topology-report/#asn=2907 ![](cid:B1BDD72A-5BEE-4A6B-B6B1-E51813AF6B05@mac.com "Screenshot 2026-05-01 at 11.12.51 AM.png") Steven Wallace Director - Routing Integrity Internet2 ssw(a)internet2.edu
