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.

Thanks

The document should recommend consistency in what NRENs announce to each other and peer NRENs and other policy goals we have in common. 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.  

Thanks

Mark,

That’s a great suggestion. 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.
