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.         Best Regards, Meral --- Meral Shirazipour Ericsson Research www.ericsson.com
