FRR Northbound Migration Roadmap

[rzalamena]

This issue will serve the purpose of tracking the current FRR efforts to implement and possibly migrate the CLI to the new northbound model.

There is a public branch for the development of the northbound here:
https://github.com/FRRouting/frr/tree/nb_conversions

Please comment here if you have plans to work on something.

Implemented (YANG model + northbound)

• bfdd

• eigrpd

• lib:

  • interface

• ripd

• ripngd

• isisd

Work-in-Progress (northbound)

• Route-map

  • lib (shared by all daemons): lib: migrate route map to use northbound #5104
  • zebra (daemon specific): yang/zebra: migrate route map to northbound #5183

• Filter (access-list, prefix-list and probably BGP as, community etc... lists)

  • lib (shared by all daemons): lib: migrate FRR filter to northbound #5323

• vrrpd: VRRP northbound conversion #5314

TODO (YANG model and/or northbound)

Thanks Rafael for opening this issue for tracking. We (VMware) will keep updating our status as comments here for tracking. We would be pushing yang files first followed by backend code changes for CLI adapting the same for static, PIM, BGP and OSPF.

Meeting note (2019/12/03):
@rwestphal has plans for fabricd but will not start now. Please, contact him if anyone wants to join efforts or take over.

#5460 for staticd Yang is ready for review.
