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 SwissIX switching platform.
Currently we tag the following information:
- Switch: Indicates at which switch a prefix has been injected into the SwissIX platform. We tag the corresponding edge switch of the port.
- Example: edge01.zrh1
- Metro: The metropolitan region corresponding to the switch
- Example: Zurich
- Country: The country corresponding to the above (in M49 format)
- Example: Switzerland
- Continent: The continent corresponding to the above (in M49 format)
- Example: Europe
This means that every prefix you will learn from the route servers will have four (additional) BGP Communities attached which will indicate location information.

Examples
A prefix has the following BGP Communities attached to it:
- 65104:2
- 65103:556
- 65102:34000
- 65101:24148
From these BGP Communities you can deduce that this particular prefix has been injected in Europe (65104:150), Switzerland (65103:756) in metro region Zurich (65102:33000) at edge01.zrh1 (65101:33150).
