Federation

[Mohan Nagandlla]

Hi team 

I have Prometheus A and Prometheus B now if I enabled the federation on B to get data from A every thing is fine I am able to get the data from A but if enabled the federation in vice versa like enabled the federation on both instances I am not getting the data on both either one I am getting 

If I queried A I am able to get the data B also but if query in B I am able to getting only B self data not getting A data even though I enabled the federation 

May I know what happen or isn't federation don't support the vice versa 

And I tough like by using remote write we can send so isn't possible to send data to Prometheus by using that option
