I am trying to test GRE and FRR and was looking for pointers on some use cases or documentation. I haven't found much in the documentation though. How much support is there for GRE and if someone could kindly provide a basic topo/test scenario to this effect?

Configure the GRE on the OS-level. With all the relevant information. Then configure the GRE int in FRRouting as you would any other interface? Usually the way you do it. ,-)
