Hi,

I have been selected as the Routing Directorate QA reviewer for this draft.

Document: draft-ietf-rtgwg-spf-uloop-pb-statement-03.txt
Reviewer: Tomonori Takeda
Review Date: April 29, 2017
Intended Status: Standards Track

Here are my comments.

Overall, the document is well organized and clear about problem statement and analysis of SPF triggers and SPF delays impact on micro-loops.

Some specific comments.

1) The document is intended to be Standards Track. I do not think it is common for such analysis document to be Standards Track.

2) Just a nits, but in page 12, it says "In the figure 5", but it seems figures are not numbered.

3) In Section 4.2. Exponential backoff, it is not clear what is a condition (or conditions) to move from FM to BM.

Thanks,
Tomonori Takeda
