Hi,

I support the adoption of draft-hegde-isis-advertising-te-protocols as a
foundation for a WG item. A per-link "Capability sub-TLV" (the term
"protocol" might be too specific here) really adds a missing piece after
RFC 5073.

Once WG document, we may discuss an additional use case suggested by
that RFC: on top of RSVP-TE support, distinguish between 3209-only and
3473-capable. Indeed, there are parameters like SRLGs that were defined
as part of GMPLS extensions: an implementation (wildly) guessing RFC
3473 support from that would not be fully wrong. Similarly, an
implementation may perfectly support 3473 even if it has not explicitly
advertise a PSC switching capability on a given link. Let us make these
explicit!

My 2 cents,

Julien
