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

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?
