I am an assigned INT directorate reviewer for draft-ietf-idr-bgpls-srv6-ext.
These comments were written primarily for the benefit of the Internet Area
Directors. Document editors and shepherd(s) should treat these comments just
like they would treat comments from any other IETF contributors and resolve
them along with any other Last Call comments that have been received. For more
details on the INT Directorate, see
<https://datatracker.ietf.org/group/intdir/about/>.

Based on my review, if I was on the IESG I would ballot this document as No Objection.  

This document is well written but has lots of information in a document of this size due to the many dependencies and references.  
My only editorial comment is I would suggest a terminology section as there are lots of acronyms that aren't defined in the document.
Having a background in Routing, this wasn't a problem for me but might be for other readers.
