Traffic Engineering for BGP Downstreams
aurologic offers ingress and egress applied BGP Communities. Egress BGP Communities are available to the customer, while Ingress ones are set by aurologic up on route import.
This document is currently WIP and some communities might be not available yet. Use with caution.
Ingress Communities
These are applied on routes received by aurologic routers.
Peering
Peering Communities are like the following:
30823:153IXP:0-3, where 30823 is the aurologic AS-SET, 153 the ASCII number of IP (ingress peering combined), IXP is the numeric identifier of the IXP, e.g. 358 for GNM-IX on PeeringDB. 0-3 is either do not announce (0) or 1-3 amount of times the aurologic ASN 30823 is prepended in the AS-PATH.
- 30823:1530000:999 -> ANY Peering received route
- 30823:153358:999 -> GNM-IX, see https://www.peeringdb.com/ix/358
- 30823:1533789:999 -> ERA-IX, see https://www.peeringdb.com/ix/3789
Private Peering
- 30823:154000:999 -> ANY Private Peering
- 30823:1541766:999 -> AS24940, Hetzner Online -> Region: FFM3.DE
- 30823:154433:999 -> AS15169, Google -> Region: FFM3.DE

- 30823:1544961:999 -> AS50629, LWLcom -> Region: FFM3.DE
Egress Communities
These are applied on routes transceived by aurologic routers, e.g. to disable upstream/peering partners or influence ingress routing.
Upstream
Upstream Communities are like the following:
30823:85ASN:0-3, where 30823 is the aurologic AS-SET, 85 the ASCII number of U in Upstream, ASN is the numeric ASN of the Carrier, e.g. 5405 for inter.link. 0-3 is either do not announce (0) or 1-3 amount of times the aurologic ASN 30823 is prepended in the AS-PATH.
Upstream Communities are passed, which means if you use the Arelion Community for Local-Preference Changes, it's distributed to our upstreams.

Peering
Peering Communities are like the following:
30823:80IXP:0-3, where 30823 is the aurologic AS-SET, 80 the ASCII number of P in Peering, IXP is the numeric identifier of the IXP, e.g. 358 for GNM-IX on PeeringDB. 0-3 is either do not announce (0) or 1-3 amount of times the aurologic ASN 30823 is prepended in the AS-PATH.
