Hi!

Just answering this first question:

(1) Section 2.0. Does the sentence, “This document adds additional BGP-LS
Attribute TLVs in order to encode SR information” imply that this document
should explicitly update RFC7752?


No.

rfc7752 is the base BGP-LS specification…some TLVs are defined there.  This
document extends BGP-LS with more TLVs to support Segment Routing…but this
is an independent extension: not all rfc7752-compliant implementations have
to support SR.

Thanks!

Alvaro.
