AS9136 BGP Communities

At AS9136 we support communities for informational and control purposes. Which communites are available to you depends on your type of connection (transit, customer or peer) with us. If you find that you are missing certain information or features, please contact us as a peer by mail at peering@wobcom.de - Transit customers are welcome to open a ticket the usual way.
