Our Route Servers have a strict filter policy for BGP announcements. You need to register downstream peers to be allowed on our RS for your peering session.
Our configuration manager uses information published by you to automatically configure your downstream peering at CNX. As the basis of the configuration, we use the AS-SET object stored in the RIR whois database and information published in the peeringdb.com database.
How to register your downstream ASN:
- Create an AS-SET with APNIC (or your RIR).
- Add all your downstream peers as members to the AS-SET.
- Register your organization with peeringdb.com.
- Add your AS-SET as the IRR Record to your peeringdb entry.

Once your configuration is added, our configuration tool will automatically detect the change and create the correct configuration for you. AS-SET naming convention is traditionally the organization name prefixed with "AS," e.g., AS-ACME. You can check if someone is already using an AS-SET by querying the whois database (see below).
You can verify your AS-SET information with the following whois command:
whois -h whois.radb.net '!iAS-ACME' # ACME AS-SET
If you do not have any downstream peers to announce to CNX, there is no need to set up an AS-SET. However, we still encourage you to create a PeeringDB entry and add your peering with CNX. This will help others discover CNX, and with increased membership and more traffic, costs can be reduced for everyone.
