I have reviewed this document as part of the security directorate's ongoing effort to review all IETF documents being processed by the IESG.  These comments were written primarily for the benefit of the security area directors.  Document editors and WG chairs should treat these comments just like any other last call comments.

This document specifies a TRILL (Transparent Interconnection of Lots of Links) intermediate system-to-intermediate system (IS-IS) sub-type length value (sub-TLV) data format for is used for reporting sets of addresses associated with a port on a TRILL switch. The Security Considerations section relies on existing RFCs for transport security of the proposed data format.

I consider this document ready for publication.
