Hi Xufeng,

Thanks for accommodating our requests.

Although this may be not necessarily described in this draft, our expectations are not only TE-enabled topology, but also abstract TE topology with SR-TE, e.g. draft-ietf-teas-actn-vn-yang section 7.2.
So, could you additionally depict an abstract node including D1, D2 and D3 with external links, for example?


The other comments to Appendix B.1 are as follows:

1. If the link between D1 and D2 is TE link, the termination-point, e.g. 1-0-1, should be also TE extended? i.e. with te-tp-id, te as defined in RFC8795 Sec. 3.3-3.5.

2. As above wrote, we prefer connectivity-matrices not for a basic TE node, e.g. D1, inside, but for an abstract node. It's useful for users to clarify how to express the explicit route for SR-TE path with node/te/te-node-attributes/connectivity-matrices/underlay/primary-path.

Thanks,
Kenichi
