CURRENT_MEETING_REPORT_ Reported by Marianne Lepp/BBN MINUTES The Open Routing Working Group met for a full day at the recent IETF meeting. The previous day, we gave a formal presentation of the architecture, which was meant to give the audience a general overview of inter-domain policy routing. During the morning ORWG session, we continued where the formal presentation left off, delving into the details of the architecture as presented in the Internet Draft. In particular, we discussed the path setup procedure, the dissemination of routing information throughout the Internet, and the methods used to reduce the amount of routing information that each router must maintain. The information reduction methods include routing at the administrative domain (AD) level and leaving the IGP to route within a domain, the virtual gateway abstraction, the "super" AD, and the hierarchical organization of route servers, where the position in the hierarchy indicates the scope of the information it maintains. The one big question still open at this point is exactly how we are going to represent addresses when there are super ADs, i.e. a hierarchy of ADs. During the afternoon session, we discussed some of the differences between IDPR and BGP, but unfortunately no BGP experts were in attendance. We were and still are hoping for critical review of the inter-domain policy routing architecture by some BGP experts. In fact, anyone with comments on the Internet Draft, please mail them to msteenst@bbn.com.
