Hi Iwase,
Looks like two ryu app file also doesnt work. I think, RYU treated as a
single context.
=
loading app app1.py
loading app app2.py
instantiating app app2.py of BGPRouter2
API method core.start called with args: {'waiter': , 'cluste
Hi Suresh,
I think it should work if no confirmation with listen ports each other.
Thanks,
Iwase

Hi Iwase,
Thanks.
I have seen in some reference projects, multiple ryuapps are used.
Example:
ryu-manager app1.py app2.py
app1.py
class Router1(app_manager.RyuApp):
# trigger bgpspeaker1 here
app2.py
class Router2(app_manager.RyuApp):
# trigger bgpspeaker2 here
Will it work?
Thank
Hi Suresh,
Hmmm...
Ryu BGP Speaker seems to be a singleton per Python process, then we cannot
spawn multiple speakers from a single Ryu application.
Just an idea, how about spawning BGP Speakers as sub-processes of your
application?
And you can communicate with them via RPC API (this API does no
Hi Iwase,
Thanks.
I am getting the below error, when i try to trigger 2 BGP Speakers from
app.py

Hi Suresh,
Hmmm... I can not yet understand why you need to setup such topology though...
You mean you need to spawn two BGP Speakers from a single Ryu application?
If you need to maintain routes separately on SDN-Rtr1/SDN-Rtr2 and need to
select the best path for each router, the per-peer local
Hi Iwase,
The use case is like below,
Rtr1---SDN-Rtr1---Rtr2--SDN-Rtr2-Rtr3
Rtr1, Rtr2, Rtr3 are traditional BGP Routers
SDN-Rtr1, and SDN-Rtr2 are BGP Speakers.
SDN-Rtr1(RYU Bgp speaker) connects to two neighbors Rtr1 and Rtr2.
SDN-Rtr2(RYU Bgp speaker) connects to two nei
Hi,
I think you need to specify the following options in order to avoid the
conflicts of listening ports.
- BGP listen host addresses (or port number)

Can we run multiple BGP Speakers in the RYU application?
