Internet2 CPS 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 CPS peer networks. All of these communities are specific to individual peer networks and do not affect routing to/from the other peer networks.

  • 65000:* - Apply this community to your prefix if you do not want CPS peer network X to send traffic to you over Internet2 CPS. Where "*" denotes the ASN of the peer network X. If your BGP import policy is also set to reject Internet2's advertisements of routes from ASN "*", you will not send traffic to network X over Internet2 CPS either.
  • 65001:* - "*" is the ASN of network X. Will pad AS-PATH towards network X 1 time.
  • 65002:* - "*" is the ASN of network X. Will pad AS-PATH towards network X 2 time.
  • 65003:* - "*" is the ASN of network X. Will pad AS-PATH towards network X 3 time.
