Hello all, I haven't tested FRR yet but was wondering whether FRR is able to form an OSPF adjacency over a GRE tunnel. I was also wondering if there was any limitation should the GRE tunnel dst ip address be resolved by a BGP prefix rather than by an IGP prefix or a static route. I am saying this as, for instance, Cisco IOSXR had and possibly still has that kind of limitation where the ospf process couldn't perform recursive lookups as such in order to then send helloes and flood LSAs ...
