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.

DescriptionBGP Extended Community
Don't announce to peering partnersrt, 65009, 65100
Don't announce to transit providersrt, 65009, 65000
Announce to specific ASrt, 65000, ASN
Don't announce to specific ASrt, 65009, ASN
Prepend 1x to specific ASrt, 65001, ASN
Prepend 2x to specific ASrt, 65002, ASN
Prepend 3x to specific ASrt, 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.

SJC10 San Jose

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)

BER02 Berlin

In Berlin, by default we add the following communities to NL-IX Route Server sessions:

34307:65151 # Do not advertise to peers connected in the Netherlands	
34307:65152 # Do not advertise to peers connected in Belgium	
34307:65153 # Do not advertise to peers connected in France
34307:65154 # Do not advertise to peers connected in the United Kingdom
34307:65155 # Do not advertise to peers connected in Denmark
34307:65157 # Do not advertise to peers connected in Luxemburg

34307:65114 # Do not advertise to peers connected in Dusseldorf
34307:65115 # Do not advertise to peers connected in Frankfurt

To remove the communities above, please use 917:49789.

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.
