Traffic Engineering Communities
We use BGP Extended Communities to provide traffic-engineering control down to each ASN.
The communities below will be stripped while exporting to our transit providers and peering partners to reduce the load of control plane.
Description | BGP Extended Community |
---|---|
Don't announce to peering partners | rt, 65009, 65100 |
Don't announce to transit providers | rt, 65009, 65000 |
Announce to specific AS | rt, 65000, ASN |
Don't announce to specific AS | rt, 65009, ASN |
Prepend 1x to specific AS | rt, 65001, ASN |
Prepend 2x to specific AS | rt, 65002, ASN |
Prepend 3x to specific AS | rt, 65003, ASN |
For example, use the communities below if you want to disable all our transit providers excluding Lumen:
bgp_ext_community.add((rt, 65009, 65000));
bgp_ext_community.add((rt, 65000, 3356));
BGP Communities to override default routing policy
As a provider specializing in Global Edge Deployment, our default policy is to ensure that the AS path is aligned and no remote connection is enabled. This may not be the best policy for all use cases, so we provide the following communities to override our default policy.
General
917:49693 # Announce to AS6939 Hurricane Electric (IPv6 Transit over IX)

917:49601 # Announce to AS1299 Arelion through AS906 DMIT (AS Path would be 1299_906_YOUR_ASN)
917:49602 # Announce to AS174 Cogent through AS906 DMIT (AS Path would be 174_906_YOUR_ASN)

Third-Party BGP Communities
Below is a list of BGP communities provided by our transit providers and IX route servers.
Please note that we have no control over these communities, so we can't guarantee that they will always be available. Also, not all of our providers have them publicly available. Please contact us for access to these documents if you need them.
One Step (opens in a new tab) maintains a list of BGP communities for many transit providers, which you can check if you need more information.
