Hi,
I'm using the following options for isolation:
privateLogDir=True
privateRunDir=True
inMountNamespace=True
inPIDNamespace=True
inUTSNamespace=True
ryu-manager --zapi-server-host=/var/run/quagga/zserv.api
ryu/services/protocols/zebra/client/sample_dumper.py
The command above works if I run it on the host, but I was looking for a more
centralized way, I wanted to get everything from the controller with a single
ryu-app.

Hi,
Sorry, I haven't writing the docs for the Zebra service yet, because this
feature is very
experimental...
For connecting to the specific Zebra daemon on a Mininet host, first, you need
to find the
path to the Zebra API socket (unix domain socket) or the TCP port for the Zebra
API.
This path or TCP port number is depending on the "configure" option when
building the Zebra
(Quagga) binaries, and mostly placed on "/var/run/quagga/zserv.api" or
"127.0.0.1:2600".
I don't know how you separate each namespaces for the Zebra daemons, please try
to start
the "sample_dumper.py" with "--zapi-server-host=/var/run/quagga/zserv.api"
option on the
Mininet host on which the Zebra daemon running.
e.g.)
$ ryu-manager --zapi-server-host=/var/run/quagga/zserv.api
ryu/services/protocols/zebra/client/sample_dumper.py
And for the naming of event classes which "sample_dumper.py" specifies, please
refer the
pydoc of the following module. The naming convention is the similar to the
OpenFlow event
classes.

Thanks for the reply, I'm running quagga on mininet and each router is
in its own namespace, I think I need to connect to one specific zebra
daemon.
Do you know where I can find other examples or a clear docs for these APIs?

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?
