Hi again Zadd,
Could you keep the Ryu-devel mailing list <ryu-devel@lists.sourceforge.net>,
please?

For the use case I assumed when implemented, please refer to the first patch of
Ryu Zebra server.
https://www.mail-archive.com/ryu-devel@lists.sourceforge.net/msg13094.html
At that time, Ryu has already supported the BGP protocol service like Quagga's
BGPd, but has no
feature for RIP, OSPF or else.
So I wondered if Ryu can communicate the existing routers by using non OpenFlow
protocols which
Quagga already has (e.g., RIP, OSPF).
Many of Ryu Zebra server features are working progress though...
> How to commute with other zebra daemons or routers.
To communicate with other Zebra daemons (e.g., RIPd, OSPFd), Ryu assumes
incoming connection via
the unix domain socket or TCP socket (see the above commit message).
On the other hand, to communicate with other routers (e.g., Cisco, Juniper,
other Quagga), assumes
the connected Zebra daemons can communicate with them, so Ryu can advertise
routes (e.g., locally
generated, from the OpenFlow networks) to other routers via the Zebra daemons.
Or directory communicate with other routers via Ryu BGP service.
Thanks,
Iwase

Your question is whether Ryu can act as multiple zebra daemons against
different Quagga's OSPFd,
right?
Tow OVS instances are connecting to single Ryu and you need to define pairs
of Ryu Zebra and OSPFd?
When I implemented Zebra service on Ryu, I didn't suppose such situation
and Zebra server instance
maintains only single DB for routes and interfaces information.
But, I haven't implement a lot of how to handle connections to Zebra
clients (e.g., OSPFd) and
received routes from clients, it just generates events to notify message
receptions.
So it might be possible to act as separated Zebra daemons if RyuApp handle
these events to act so.
(Sorry, I have no plan to implement it though...)
Thanks,
Iwase

Hi,
Thanks for the help before. I still have some questions about the zebra
service. For a
hybrid topo of several ospf routers and sdn switches like this:
router---ovs----router
| | |
| | |
ovs--router---------router
sdn switches and routers are crossly deployed. Can zebra service handle
this situation.
is it possible to make ryu act as multiple zebra daemons to parse ospf
messages from
different sdn switches so as to make the sdn switches or areas act
like a router.

Hello
I am working on the hybrid SDN network(routers
connected to ovs). I'm
wondering if I can use the zebra protocol in ryu to deal
with the packet_In OSPF
message from the router connected to the ovs. If not，could
you please
enlighten me how
i can make the hosts in ospf area and openflow area
communicate with each other.
I guess receiving OSPF packets via Packet-In is difficult.
How about adding an additional port which OSPFd listening on?
For example, the following topology has a port which
connecting to OSPFd's
interface and
forwards
OSPF packets for OSPFd then Ryu communicates with OSPFd via
Zebra daemon.
(Also, Ryu can acts as Zebra daemon against OSPFd, I guess.)
+---Zebra---+

(Open Flow) (Open Flow) (OSPF pcakets)

I'm looking forward to your reply.
Thanks,
