Informational BGP Communities

Route Origin

The route server will mark all routes with certain BGP Communities to indicate their origin. You can use this information to determine where a certain route has been injected into the SwissIX switching platform. This gives you the option 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 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 route you will learn from the route servers will have four (additional) BGP Communities (per community class, e.g. each Standard and Large respectively) attached which will indicate location information.
