Hi,
How about using the Zebra client service library of Ryu?
https://github.com/osrg/ryu/blob/master/ryu/services/protocols/zebra/client/sample_dumper.py
This library provides the APIs to communicate with the Zebra daemon of Quagga
(or FRRouting).
For example, if you need "connected" routes in your Ryu application, the
following dumps the
"connected" routes which the Zebra daemon redistributed.

Hi, I'm running Quagga on my mininet topology to capture routing
information, I wanted to know if it's possible to retrieve the routing
table on the quagga routers (which are basically mininet hosts) or at
least the flow tables. If so, how do I do it?
