AqabaIX route server Informational BGP Communities
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 AqabaIX switching platform.
Currently we tag the following information:
Switch: Indicates at which switch a prefix has been injected into the AqabaIX platform. We tag the corresponding edge switch of the port.
- Example: edge01.aqj1
Metro: The metropolitan region corresponding to the switch
- Example: Aqaba
Country: The country corresponding to the above (in M49 format)
- Example: Jordan
Continent: The continent corresponding to the above (in M49 format)
- Example: Asia
This means that every prefix you will learn from the route servers will have four (additional) BGP Communities attached which will indicate location information.
To avoid ambiguity about the semantics of a certain BGP Community, especially when being present multiple times, we strip all BGP Communities from the range that we use for route origin tagging on import. This is:
|Continent||M.49 Region Code (Continent)||Continent BGP Com||Country||M.49 Region Code (Country)||Country BGP Com||Metro||Metro Code||Metro BGP Com|
Switch BGP Com
A prefix has the following BGP Communities attached to it:
From these BGP Communities you can deduce that this particular prefix has been injected in Asean (65104:142), Jordan (65103:400) in metro region Aqaba (65102:43000) at edge01.tip1 (65101:43162).
