Hi Zadd,
Please keep mailing list <ryu-devel@lists.sourceforge.net>.
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---+
| |
+-----------Ryu OSPFd
| | |
(Open Flow) (Open Flow) (OSPF pcakets)
| | |
(OpenFlow NW)----OVS----------+
|
+----------(OSPF NW)
Thanks,
Iwase
I'm looking forward to your reply.
Thanks,
zadd
