VISUALIZING IPV4 & IPv6 GLOBALLY AND WITHIN EUROPE

27 Sept 2012 3 Martin J Levy - Hurricane Electric - Intercountry BGP As Topology

Checking global IPv6 routing – graphically!


http://bgp.he.net/

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.

Showing IPv4/IPv6 route propagation in a graphical form

http://bgp.he.net/ – Route propagation graphs


Peers that see routes

ASN originating routes

Routes see downstream

of peers

Select tab for v4 or v6 graphs

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 http://bgp.he.net/ processed further   Graphical view on a country-to-country basis


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 http://bgp.he.net/ site and it’s database   Daily processing of those BGP tables   Results are user-friendly visualization of routing

  Take the data one step further …


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


Example processing – CC & ASN


http

://bg

p.he

.net

/cou

ntry

/MY

Process each A

SN

within each country

Note the ASNs within the country …

http://bgp.he.net/AS24514#_peers

Rem

ove all peers within C

C Note the peer connections that are

outside the country …

  Full country listing at http://bgp.he.net/country/GB (not UK)   Assuming that the ASN is listed as “GB” within RIPE database

Visualizing IPv6 routing within the UK


ASNs sorted by Adjacency count

http://bgp.he.net/country/GB

  Routing propagation graphs for three providers in the UK   These change all the time; it’s best to look online for latest BGP propagation



Caveat: Not all links will show within these graphs

Does this produce valid BGP diagrams?

  Can you question the collected BGP data?   Yes - There’s a need for more participating ASNs

  Can you question the quality of the data?   Yes - BGP is BGP – it’s only “best path”

  Can you question the processing?   Yes - It only takes one route to show an adjacency exists

  Can you question a connection from CC1 to CC2?   Yes – in some cases peering could be in CC3 (ie: USA)
