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
