I have reviewed this document as part of the Operational directorate's
ongoing effort to review all IETF documents being processed by the
IESG. These comments were written with the intent of improving the
operational aspects of the IETF drafts. Comments that are not addressed
in last call may be included in AD reviews during the IESG review.
Document editors and WG chairs should treat these comments just like
any other last call comments.

Summary: this document is ready

This draft describes a mechanism for reducing the number of BGP MAC
advertisement routes, provide MAC address mobility, and several other
MAC handling enhancements, using Ethernet Provider Backbone Bridging
combined with Ethernet VPN.  This work appears to provide significant
improvements to both network resource usage and in MAC address
manageability.

Overall the document is a bit thin on material on network management,
although the material describing the behavior of the mechanisms being
used in the context of different kinds of failures is quite good.

The document is very clearly written and the material describing
protocol operation/behavior is much appreciated.  The PBB-EVPN
mechanism appears to be an enormous win for very large data centers.

Passed the nits tool with only a warning about the publication year
not matching the current year.

This document was a pleasure to read.
