Northbound changes discussion - MOM 13/12/2019

[Santosh P K]

Hello All,
    Below are the points discussed and concluded in today’s meeting.

Discussion:

  1.  Went over static yang model that has addressed last week comments.
  2.  Currently static yang has its own nexthop defined as we could not use nexthop defined in frr-nexthop.yang.
     *   Frr-nexthop.yang is having only groupings and this would not help for other modules to extend/deviate the same.
     *   Frr-nexthop.yang should be changed and static should make use of the same.
  3.  Code for handling nexthop-group should be part of the library which right now is sitting under zebra so that all the other modules can leverage it.
     *   Mark may have plans for making it a library.
  4.  Port only required IETF yang files in separate PR categorized per protocols.
  5.  Discussed on VRF and how should this be used.
     *   Discussed over network instance defined in IETF. Discussed over restrictions of network-instance in libyang.
     *   Renato will be trying with deviation and see if we can get a workaround for this problem.
     *   Lou suggested to use network instance manually.

Conclusion:

  1.  Agreed to change the exiting frr-nexthop.yang to have common container of nexthop and nexthop-groups. Have only minimum set of leaf which are common across all the modules. Augment/deviate this in protocols as they need.


We will meet again on Wednesday 18th Dec 2019 at 8:00AM PST for VRF discussion.


Thanks
Santosh P K
