FRR with confd or sysrepo

[TeSwen]

Now that the FRR includes libyang and yang models, where do we go from here? Is there any documentation on how you use confd or sysrepo as netconf servers with the FRR? I think it comes down to the fact that once you have yang models that's great but what you really need is instance data before anything meaningful can happen with FRR/Netconf/Yang. So this leads to the question of how does one create instance data for say, the frr-ospfd model? This doesn't appear trivial. Pyang and yanglint aren't able to get it done. Has anyone gone through this successfully?
