Informational BGP communities

Route origin

The route server will tag all prefixes with certain BGP Communities to indicate their origin. You can use this information to determine where a certain prefix has been injected into the DE-CIX switching platform. This gives you the possibility to filter routes learned from the route servers based on geographical location. 

Currently, we tag the following information:

Switch: Indicates at which switch a prefix has been injected into the DE-CIX platform. We tag the corresponding edge switch of the port.

  • Example: edge01.fra2

Metro: The metropolitan region corresponding to the switch.

  • Example: Frankfurt

Country: The country corresponding to the above (in M.49 format).

  • Example: Germany

Continent: The continent corresponding to the above (in M.49 format).

  • Example: Europe

This means that every prefix you learn from the route servers has four (additional) BGP Communities attached which indicate location information.

BGP communities graph

To avoid ambiguity about the semantics of a certain BGP Community, especially when present multiple times, we strip all BGP Communities from the range that we use for route origin tagging on import. This is:

  • 65101:*
  • 65102:*
  • 65103:*
  • 65104:*

  • 65104:142
  • 65103:792
  • 65102:8000
  • 65101:8056

From these BGP Communities you can deduce that this particular prefix has been injected in Asia (65104:142), Turkey (65103:792) in metro region Istanbul (65102:8000) at edge01.ist1 (65101:8056).

Example 3
A prefix has the following BGP Communities attached to it:

  • 65104:019
  • 65103:840
  • 65102:2000
