Hi, I have not had time to review the full document yet, but I do have some immediate comments. In Section 3, 4th para, we *do* build routers to meet today's requirements and so it is unnecessary to ask a question that has already been clearly answered in the affirmative. In Section 3.1, first para, the wording here leaves out the most important "must", which is that routers must process changes to the network topology. Moreover, it leaves as quite murky as to whether the problem is in the forwarding path, the update path, or both, or whether this is dependent on design architecture. I would personally like to see some performance numbers here. In Section 4.3 first para, last sentence, given current discussions on RAM, I would make the following change for clarity: OLD: > However, each individual PI > prefix must be propagated throughout the DFZ and adds to the DFZ > routing load. NEW: > However, with the current BGP-based routing system, each individual PI > prefix must be propagated throughout the DFZ and adds to the DFZ > routing load. Section 4.4 should reference (informationally) RFC 1627, where we first raised this concern 13 years ago. Finally, in Section 6, I think we should add that it is desirable that those who multihome or make use of traffic engineering incur whatever associated costs. This follows in part from your earlier business alignment discussion. Eliot _______________________________________________ RAM mailing list RAM@iab.org https://www1.ietf.org/mailman/listinfo/ram
