Document:  draft-ietf-idr-add-paths-13
Reviewer: Meral Shirazipour
Review Date: 2016-04-28
IETF LC End Date: 2016-04-29
IESG Telechat date: 2016-05-05


Summary:
This draft is ready to be published as Standards Track RFC but I have some comments.

Major issues:

Minor issues:
-[Page 2] The introduction should give a hint of why this extension is necessary. Section 6 (Application) is pretty much empty in content too.
It would be important to add a few lines explaining the use cases and if any draft is started on those to give a pointer to them.
*An "Add-Paths Applications" section would be useful like the one in draft-ietf-idr-add-paths-guidelines-08.


-[Page 3],
"A BGP
   speaker that receives a route SHOULD NOT assume that the identifier
   carries any particular semantics; it SHOULD be treated as an opaque
   value.
"
*It would be good to justify why this restriction is imposed. If someone is using BGP add-Path internally, why prevent giving some semantics to the encoding?


-[Page 6], security section refers to Information guideline draft (draft-ietf-idr-add-paths-guidelines-08).
Is this draft also for IBGP only ? this was not clear.


Nits/editorial comments:
-[Page 7], References should be updated to newer versions.
