question: What API to use zAPI, mgmt_fe_client or gRPC to build an external configuration daemon

[mattiaswal]

Hi all,
In Infix I want to implement a small daemon that injects route configuration to FRR (from our configuration or from DHCP clients). For this i am wondering which API I should use, gRPC seems like the new future way, but it also seems like the correct way to do as vtysh, to use the mgmt_fe_client, but that is hard coded to not work in the FRR code.

So i guess i should go for gRPC?

So, is there a "correct" way to do this with FRR?
