I'm not sure how that is helpful.
If Internet2 indicates that it is providing transit to Géant then as far as building filters is concerned that is different to Internet2 indicating who its customers are as the customer set should include all prefixes and as-paths I might see but the as-nren-peers set will not. If you are building filters via a RPSL tool then these export policies are different.
This was the same path I was going down. If the goal is to build filters via RPSL, you would need to stitch together the IRR objects representing the customer cone of each peer.

Dave,
I’ll update the document to be clearer. I’m suggesting that AS11537:AS-NREN-PEERS contains the ASNs of Internet2’s NREN peers, not their customer cones. For example, AS11537:AS-NREN-PEERS would contain AS20965 (GEANT), among others. It wouldn’t contain AS20965:AS-CUSTOMERS or AS20965:AS-NREN-PEERS.

Steve, In rereading it, in your example for Internet2, do you anticipate AS11537:AS-NREN-PEERS to be made up of the customer cones of the NRENs Internet2 will provide transit too? For example, AS11537:AS-NREN-PEERS = AS7575:AS-CUSTOMER, AS6509:AS-CANARIE, AS-CERNEXT, ... I ask because there are limits to the depth of how many references to references to references can be made for most RPSL tooling. So you should probably cover that issue in the discussion.

I have seen it several times where an NREN doesn't announce a prefix to one peer but does to another peer, causing traffic to go the wrong way around the globe. Actually, documenting the prefixes and the relationships will go a long way to resolving many of these issues. Nevertheless, we should recognize and document our common policy goals in addition to the mechanisms used to achieve the goals.

I believe Internet2 used to publish a set of community tags that attempted to provide this capability. I’m looking through old records to see if there is anything worth reusing or learning from.

As an example it would probably be helpful for Géant to know if Internet2 is sending prefixes from South America or Africa as they possibly have a better path to those locations and would want to depreference an Internet2 version even if the AS path was shorter. If there are regions with limited connectivity options than enumerating them might be helpful. > > Mark.
