Reviewer: Shwetha Bhandari Review Result: Ready with one nit 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 specifies the support of P2MP BFD in TRILL. This document extends RFC 7175 TRILL BFD Support to P2MP BFD being defined by draft-ietf-bfd-multipoint. There is no operational considerations or manageability section in the document. I don’t see any operational, network management concerns with this document. For security consideration the concern raised here [https://mailarchive.ietf.org/arch/msg/trill/VcoPfBXqDG3K5cuydXqQ7juv9Rg] there is new proposed text that needs wg review. The new text proposed to use TRILL RFC 7978 authentication instead of current recommendation of BFD multipoint authentication. Nit: Section 6 – In : See [I-D.ietf-bfd-multipoint-active-tail] for detail operations of tacking active tails. s/tacking/tracking Thanks, Shwetha
