Hi authors,

From our applicability consideration of this draft, we would like you to add CoS attribute to path-constraints if it's reasonable.
Regardless of DS-TE implementation, our usecase wants to specify the CoS as one of path-constraints. 

RFC8776 only defines the type of te-ds-class, but it is not used in te-types:generic-path-constraints.

At this time, we believe it's enough to just augment to add like this?
augment /ietf-te-types:path-constraints:
  +--rw leaf path-cos?    te-ds-class;

Typo:
Although I don't fully check , in Sec. 7.2. TE-topology JSON example, networks/network/te-topology-id should be networks/network/topology-id according to RFC8795/8776, te-types:te-topology-identifier.

Thanks,
Kenichi

Hi WG,

Following changes are made in this update -

- Resolved the issue with /ap/ap/.. and /vn/vn/.. in the YANG model
- Added an empty container "underlay" with this text - Note that the YANG model is tightly coupled with the TE Topology model [RFC8795<https://www.ietf.org/archive/id/draft-ietf-teas-actn-vn-yang-12.html#RFC8795>]5>]. Any underlay technology not supported by [RFC8795<https://www.ietf.org/archive/id/draft-ietf-teas-actn-vn-yang-12.html#RFC8795>] is also not supported by this model. The model does include an empty container called "underlay" that can be augmented. For example the SR-policy information can be augmented for the SR underlay by a future model.
- Updated the description for vn-compute-status

<tp>

I like the changes in the identifiers!

s.1.3
wrong prefix for te-topo.  The YANG module import is ok.

Tom Petch

See https://www.ietf.org/rfcdiff?url2=draft-ietf-teas-actn-vn-yang-12

Thanks!
