1 Intercountry BGP As Topology DKNOG3 Copenhagen, Denmark 21 st March 2013 Pretty diagrams are good! Martin J. Levy, Director IPv6 Strategy Hurricane Electric

2 Agenda Not the same-old same-old IPv6 talk Today I ll show pretty IPv6 topology pictures The methodology The visualization IPv4 & IPv6 BGP adjacency Show within countries and between countries Summary 21 March 2013 Martin J Levy - Hurricane Electric - Intercountry BGP As Topology 2

3 BUT FIRST A WORD ABOUT IPv6 21 March 2013 Martin J Levy - Hurricane Electric - Intercountry BGP As Topology 3

4 WORLD IPv6 DAY & 2012 WORLD IPv6 LAUNCH IPv6 TRAFFIC BY THE NUMBERS 21 March 2013 Martin J Levy - Hurricane Electric - Intercountry BGP As Topology 4

5 IPv6 measured at via BGP ASNs with IPv6 Networks Running IPv6 We can measure the percentage of networks running IPv6 by comparing the set of ASes in the IPv6 routing table to those in the combined set of IPv4 and IPv6. IPv4 and IPv6 RIBs Last Parsed: Sat Jan 26 01:02:18 PST % IPv4 ASes: IPv6 ASes: 6686 ASes using only IPv4: ASes using only IPv6: 126 ASes using IPv4 and IPv6: 6560 ASes using IPv4 or IPv6: Percentage of ASes (IPv4 or IPv6) running IPv6: 15.4% 15% 14% 13% 12% 11% 10% 9% 8% 7% 6% 5% 4% 3% 2% 1% 0% 3.6% 15.4% IANA Runout W6D W6L 07/ / / / / / / / / / / / / / / / / / / March 2013 Martin J Levy - Hurricane Electric - Intercountry BGP As Topology 5

6 Is IPv6 routing/interconnect/peering prevalent? ~55% average increase per year! ~33% average increase per year! 21 March 2013 Martin J Levy - Hurricane Electric - Intercountry BGP As Topology 6

7 But first 2011 IPv6 Day Continued long-term win since W6D in IPv6 traffic levels That means there are both content and eyeballs are in play Routing improvements since June/2012 Additional peering implemented (ie: IPv6 following IPv4) 21 March 2013 Martin J Levy - Hurricane Electric - Intercountry BGP As Topology 7

8 2012 IPv6 Launch - real IPv6 traffic Continued long-term win since W6D in IPv6 traffic levels That means there are both content and eyeballs are in play Routing improvements since June/2012 Additional peering implemented (ie: IPv6 following IPv4) 21 March 2013 Martin J Levy - Hurricane Electric - Intercountry BGP As Topology 8

9 VISUALIZING IPV4 & IPv6 GLOBALLY AND WITHIN EUROPE 21 March 2013 Martin J Levy - Hurricane Electric - Intercountry BGP As Topology 9

10 Checking global IPv6 routing graphically! Showing IPv4/IPv6 route propagation in a graphical form Caveat: - This tool is only as good as its source data. - IP information is uploaded from RIPE RIS & Oregon routeviews. - Some views are missing; not all routes and paths are visible. - NOT based on the Hurricane Electric routing tables. 21 March 2013 Martin J Levy - Hurricane Electric - Intercountry BGP As Topology 10

11 Route propagation graphs Select tab for v4 or v6 graphs Peers that see routes Routes see downstream of peers ASN originating routes 21 March 2013 Martin J Levy - Hurricane Electric - Intercountry BGP As Topology 11

12 Can regional IPv6 routing be measured? Question: Is there enough IPv6 routing between ISPs? Can IPv6 BGP routing tables provide insight? Methodology: Lots of BGP routing tables collected globally Data from processed further Graphical view on a country-to-country basis 21 March 2013 Martin J Levy - Hurricane Electric - Intercountry BGP As Topology 12

13 Measuring BGP routing by collecting tables Build on exceptional work by others RIPE/RIS & Oregon routeviews collect BGP tables A hearty thank you to RIPE & University of Oregon Use Hurricane Electric s site and it s database Daily processing of those BGP tables Results are user-friendly visualization of routing Take the data one step further 21 March 2013 Martin J Levy - Hurricane Electric - Intercountry BGP As Topology 13

14 Measuring BGP routing by collecting tables Take the data one step further Only look at BGP peer data (v4 & v6) It s only interesting to look at BGP adjacency Map ASN to country-codes Search for adjacencies where CCs are different Process resulting data to search for in-region connections Clean up the data Display the data 21 March 2013 Martin J Levy - Hurricane Electric - Intercountry BGP As Topology 14

15 Example processing CC & ASN Note the ASNs within the country Process each ASN within each country Note the peer connections that are outside the country Remove all peers within CC 21 March 2013 Martin J Levy - Hurricane Electric - Intercountry BGP As Topology 15

16 Visualizing IPv6 routing within a country Full country listing at Assuming that the ASN is listed as $CC within RIPE database ASNs sorted by Adjacency count 21 March 2013 Martin J Levy - Hurricane Electric - Intercountry BGP As Topology 16
