Hi! As a member of the Operations Directorate I have reviewed the following draft which is in IETF last call for it's operational impact. This document specifies the data formats and code points for the IS-IS extensions to support TRILL. The base protocol is specified in RFC 6325, and this document obsoletes RFC 6326. Summary: Ready with nits This is a really well written document. It addresses operational considerations of backwards compatibility of the new protocol constructs defined. Other considerations for operational impact are covered in the base protocol. Nits: RFC 5342 was obsoleted by RFC 7042 and the pointer should probably be updated. Thanks, -- Carlos.
