I am the assigned Gen-ART reviewer for this draft. For background on Gen-ART, please see the FAQ at <>
Document:                       draft-ietf-isis-remaining-lifetime-02
Reviewer:                         Christer Holmberg
Review Date:                   6 August 2016
IETF LC End Date:            15 August 2016
IETF Telechat Date:        N/A

The document is well written, and almost ready for publication as a standards track RFC, but I have a couple of editorial comments that I'd like the authors to address.
Major Issues:    None
Minor Issues:    None
Editorial Issues:
The Abstract says:
"Corruption of the Remainining Lifetime Field in a Link State PDU can go undetected.  In certain scenarios this may cause or exacerbate flooding storms.  It is also a possible denial of service attack vector.  This document defines a backwards compatible solution to this problem."
...and the first sentence of the Problem Statement says:
"Each Link State PDU (LSP) includes a Remaining Lifetime field."
I have no idea what a Link State PDU is, and there is no introduction to what the draft is all about. The text jumps direction into the work.
So, please add a reference to Link State PDU (LSP), and please give a little bit of introduction text what context/environment this is all about. I assume there is some core document which describes the context/environment where the Link State PDU is used?
