Hi Hannes,

I agree with you but if draft-kini-mpls-spring-entropy-label evolve to the option where entropy label is always behind top label, there is no need to encode such granularity.
That's why I think it's too early to progress the capability document.

Thoughts ?

Stephane

<IS-IS WG chair hat off>

i'm discomfortable with the *granularity* of the cap-advertisement:

rather than saying:

"i can crawl as deep as you like on any of my interfaces"

  i'd like to announce:

"i can crawl for EL <N> up to labels deep on interface XYZ"

Since (http://tools.ietf.org/html/draft-ietf-isis-segment-routing-extensions-00) has been adopted as a WG draft, as co-authors of draft-xu-isis-mpls-elc-00, we hope you could consider the WG adoption for this draft as well.
