Hi all:

I have performed an Operations Directorate review of
   draft-ietf-isis-sbfd-discriminator-02

  "This document defines a new optional Intermediate System to
   Intermediate System (IS-IS) TLV named CAPABILITY, formed of multiple
   sub-TLVs, which allows a router to announce its capabilities within
   an IS-IS level or the entire routing domain."

- - - -

This is a straightforward and clear draft, defining a new IS-IS sub-TLV.
I wondered whether routers that didn't know about this might have
problems with it, but I see that RFC 4971 covers this well.
I also wondered wy this draft doesn't describe how te BFD sub-TLV
is laid out in its Value field, but I see that's covered in RFC 5305.

So, overall a good document, fit for its intended purpose, and ready for
publication.

One tiny typo:
  s2  s/S-BFD Discriminators sub-TLVs are formatted/
        S-BFD Discriminator sub-TLVs are formatted/

Cheers, Nevil
Co-chair, SUPA WG
