Internet2 BGP Communities

 

Internet2 External Traffic Influencing Communities

 

International, Non-International, or FEDNET peers may send the below community and we will set their localpref to 40 or 160 respectively:

  • Default - 100
  • 11537:40 - Low
  • 11537:160 - High

Connectors may send the below community and we will set their localpref to 140 or 260 respectively:

  • Default - 200
  • 11537:140 - Low
  • 11537:260 - High

 

Internet2 Peers may send the following communities:

  • 11537:2002 - Block prefix to commercial R&E peers.

Internet2 International (ITN) peers may send the below communities for path prepending:

  • 65001:65000 - prepend x1
  • 65002:65000 - prepend x2 
  • 65003:65000 - prepend x3 

 

The following community combination of <CODE>:<ASN> allows you to block or prepend prefixes sent to individual international (ITN) peers.  This is in the process of being deployed, once a peer has had the necessary configuration added, their ASN will be added here.

  • Codes:
    • 65000     - prefixes will not be sent to ITN peer’s ASN
    • 65001     - prefixes will be prepended 1 time to ITN peer’s ASN
    • 65002     - prefixes will be prepended 2 times to ITN peer’s ASN
    • 65003     - prefixes will be prepended 3 time2 to ITN peer’s ASN
    • 65012     - prefixes will only be sent to ITN peer's ASN
  • ITN Peer ASN:
    • 2603     - NORDUnet
    • 20965     - GEANT

 

 

Internet2 Internal Traffic Influencing Communities

 

Internet2-connected Gigapops and connectors with heterogeneous participants (i.e. not all are universities) may need to use these communities to help them pass prefixes appropriately to their participants.  For example, connectors can pass all prefixes on to their university participants, but should not pass commercial or US Fednet prefixes to their commercial or Fednet participants. 

  • 11537:888 - Block to external (Internet2 uses this community to mark prefixes that will not be reannounced to external peers).
  • 11537:902 - non-I2 R&E sites sponsored for connection by members.
  • 11537:910 - sponsored educational groups (Primary state networks).
  • 11537:911 - Blackhole. Traffic to these prefixes will be discarded.
  • 11537:950 - Internet2 Participants.
  • 11537:2000 - Commercial research - Lab participant.
  • 11537:2001 - Special Commercial prefix used for V6 or multicast.
  • 11537:2500 - Block advertisement to international.
  • 11537:2501 - International.
  • 11537:3000 - FEDNET (US Federal Peer Network).
  • 11537:3500 - Connector Only (Internet2 uses this to mark prefixes sent to connectors but not peers).
  • 11537:4000 - RHCPP (Rural Health Network Groups).
  • 11537:6001 - LHCOne Connectors.
  • 11537:6002 - LHCOne Peers
  • 65535:666 - Blackhole.  Traffic to these prefixes will be discarded.

NET+ BGP Communities

Internet2 has implemented a set of BGP communities that, along with your own local BGP import policy, will allow you to control your traffic path to/from the Internet2 NET+ peer networks. All of these communities are specific to individual peer networks and do not affect routing to/from the other peer networks.
