The MREN Catalyst 6509 switch at the StarLight facility is the first piece of equipment that will operate in BGP Autonomous System (AS) 22335. This AS will be used to transit traffic between a number of Illinois, national and international networks. As a transit AS, no packet filtering will be applied. Firewall policies are the responsibility of the peer networks and institutions. AS 22335 will also be the Abilene connector for MREN. As such, it will follow the Abilene re-advertisement policies, such as those applicable to federal laboratories with agency network backbones.

Peer Categories
Abilene Participant MREN Institutions
One of the primary motivations for AS 22335 is to connect Midwest institutions to Abilene. That is, AS 22335 will be an Abilene connector for these networks. Abilene participants may be regular, corporate, or federal; each of which have differing re-advertisement criteria.

Abilene
Abilene maintains a unique policy regarding advertisements it will accept, and will be treated as a special case.

Non-Abilene Participant MREN Institutions
Some AS 22335 participants are not Abilene participants, and are thus ineligible to receive Abilene routes. However, they should receive announcements for all other routes.

High Performance Research Networks
STAR TAP, ESNet, vBNS+, CANARIE and other networks will peer. They do not have the strict advertisement criteria of Abilene, and can thus be treated alike.

Commercial ISPs
The set of AS 22335 peers may be attractive to regional commercial Internet Service Providers (ISPs) for direct peering. Prefixes received from commercial ISPs will never be chosen over any other route, even if the AS path length is shorter.

GENUITY from STAR TAP
STAR TAP gets commodity transit from GENUITY. These routes should never be re-advertised to any AS 22335 peer.
