Hi Vasiliy,

OVN doesn't yet support tunnel interconnection between different OVN
setups. It would be a great feature to support routing between logical
routers from different OVN setups through tunnels between gateways. I think
it shouldn't be too difficult to support this in OVN.

If you require a L2 network (logical switch) spanning multiple OVN setups,
it might be more tricky. (if so, what's the use case?)

Thanks,
Han
