Hi Ketan

Thank you for updating the draft and I do like the more appropriate name
change from

“ North-Bound Distribution of Link-State and Traffic Engineering (TE)

                         Information Using BGP”


*To*


*Distribution of Link-State and Traffic Engineering Information Using BGP*



Few comments.

In RFC 7752 where does in mention BGP-LS AFI/SAFI?

I think it should be added if missing.

Also since the same

71 BGP-LS [RFC7752 <https://www.iana.org/go/rfc7752>]
72 BGP-LS-VPN

Also the SR BGP-LS extension uses the same AFI/SAFI above maybe mentioning
normative reference to the SR BGP-LS extension.

I think we should add the AFI/SAFI reference to the draft below.

https://tools.ietf.org/html/draft-ietf-idr-bgp-ls-segment-routing-ext-16

Also in the abstract mentions Traffic Engineering referring to RSVP TE and
then in the introduction mentions TEDs.  As referring to TE could mean
RSVP-TE or SR maybe in the abstract state RSVP-TE as this specification is
strictly for RSVP-TE.

Kind Regards


Gyan
