[FROG] GRPC support for BGP, OSPF, RIP and OSPFV3 daemons

Hi All, I wanted to understand the current status and future plans for FRR GRPC Northbound support. I followed the developer guide to get the taste of grpc and looking at the frr test code i was able to do basic static configuration and fetch the configuration using get APIs. But when I tried the same thing on BGP I didn't get any configuration as response(although I configured bgp using VTYSH and also enabled GRPC on bgpd). Due to lack of clarity from the documentation I skimmed through the code, as per my understanding not all the daemons contain the code to support GET and SET APIs as of now. Is my understanding correct? Please point me to any development branch where GRPC support work is going on. Thanks in advance, Jagadeesh N
