Hi Les,

The proposal has a better shape. Still two comments:
- As mentioned earlier, please precise that LFA means any flavor of LFA (LFA,rLFA,dLFA,TILFA...). 
- I would also like to see that "standard" applications may also use UDAs instead of the standard bit and possibility two sets of attributes (two UDAs or 1 std + 1 UDA): one example could be having an SR-TE tunnel using a particular set of attributes, and another SR-TE tunnel using another set of attributes.

Folks -

This new version adds support for using a set of link attribute advertisements for ANY application - something which the OSPF companion draft (draft-ppsenak-ospf-te-link-attr-reuse) supports.
It also aligns the encoding so that is similar to that defined in the OSPF draft.

A new version of I-D, draft-ginsberg-isis-te-app-03.txt has been successfully submitted by Les Ginsberg and posted to the IETF repository.

Name:		draft-ginsberg-isis-te-app
Revision:	03
Title:		IS-IS TE Attributes per application
Document date:	2017-06-20
Group:		Individual Submission
Pages:		15

   Existing traffic engineering related link attribute advertisements
   have been defined and are used in RSVP-TE deployments.  In cases
   where multiple applications wish to make use of these link attributes
   the current advertisements do not support application specific values
   for a given attribute nor do they support indication of which
   applications are using the advertised value for a given link.

   This draft introduces new link attribute advertisements which address
   both of these shortcomings.  It also discusses backwards
   compatibility issues and how to minimize duplicate advertisements in
   the presence of routers which do not support the extensions defined
   in this document.


Please note that it may take a couple of minutes from the time of submission until the htmlized version and diff are available at
