Reviewer: Stewart Bryant Review Date: 2017-06-28 IETF LC End Date: 2017-06-28 IESG Telechat date: 2017-07-06 Summary: This is a well written document. I do however have a concern with the scaling text in section 1.2.x, as I think this could be more accessible and ought to include discussion of MAC Address scaling. More information below. Major issues: None Minor issues: The key justification for multi-area is scaling. The scene is set in Section 1.2.x. However there are no references, the design size parameters are not articulated for each case, and the equations are not derived. I think that it would be helpful if the draft either provided some more explanation of the scaling equations and the associated input assumptions, or provided the assumptions and directed the reader to an accessible text to understand the equations. Although there is some discussion on it later there is no discussion of the number of addresses to be learned in the single and multi-area cases and the impact this has on the LSDB. The number of addresses to be learned will impact the ingress RBridge FIB and the FIB update time so this is just as significant in understanding the benefit of multi-level as understanding the link-state convergence time is.
