Thanks Paolo!

I’ll look into the bgp_agent_map.

In this case, both route servers *should* contain the same routing information 
however they will never be perfectly symmetrical.
I’ll peer with the “primary” RS for now but I’ll be looking into a GoBGP daemon 
to feed BMP data into pmacct instead of direct peer. 

Also, is there a way to feed BMP and flow data into pmacct off a Kafka bus? It 
would be good to buffer input data streams into pmacct to allow for better data 
buffering and system resiliency?
