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], 


   speaker that receives a route SHOULD NOT assume that the identifier

   carries any particular semantics; it SHOULD be treated as an opaque



*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.
