MPLS-TE YANG meeting #2 Wednesday 12/10 @ 7:00pm EST
Project wiki: https://github.com/ietf-mpls-yang/te/wiki/MPLS-TE-YANG

The group met on Wednesday 12/10. Below are minutes/notes. Next meeting is scheduled for Thursday 12/18.

Meeting Summary
. team progressed with TE link data model
  a. In addition to the reference models (non-final), the following models were created and checked-in:
     - ietf-mpls-te.yang
     - ietf-mpls-te-types.yang
     - ietf-mpls-te-rsvp.yang

. Work-in-progress for TE link model was discussed
    - Base MPLS-TE link data reperesentation to be added in ietf-mpls-te.yang
    - RSVP-TE specific link data extensions to be added in ietf-mpls-te-rsvp.yang
    - Common grouping to go in iet-mpls-te-types.yang. Other models can import and reuse.

. Team to review the checked-in of the models above and make modifications as needed.
- to discuss changes/additions in next meeting

. Discussed possibility of having the top of the MPLS-TE tree off a routing instance

. Tools
- to use github syntax highlighted diff feature https://github.com/blog/1932-syntax-highlighted-diffs
- to use github to add comments inline into the new diffs
- to use github to report issues and notify

. Next steps/AIs:
    - Team: to review/add/update link data node in the model
    Pavan will share comments.

. To use if-feature for vendor specific supported features
- [email-masked] to report if-feature can still be used with choice/case

. RSVP Yang model
- The point of defining RSVP groupings and an RSVP (non-TE) YANG model was discussed
a. Need to be able to enable RSVP on interface for non-TE (e.g. IPv4 flows)
b. May require defining module in ietf-rsvp.yang. Module ietf-mpls-te-rsvp.yang can import
AIs: to send email to alias /WG-chair’s to get their thoughts on defining RSVP-specific YANG module (e.g. etf-rsvp.yang module) that ietf-mpls-te-rsvp.yang can import.
