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.
