Hi, Ukeme
At first, you seem to use an old version of Ryu.
The latest version of Ryu is 4.14. Please check and update:
$ ryu-manager --version
Then, argument "--bgp-app-config-file" should be work.
And the configuration file for the bgp application (bgp_sample_conf.py)
provides various setting items.
Please check it is enough for you.
If it is not enough, please ask me what you want to do to.
We can tell you where to change the application.
>My questions are:
1)Could this be accomplished using only ryu and mininet?
Yes, I think.
2)Do I need to integrate quagga or bird into this ryu application?
If you are interested in only bgp messages, not the communication
between hosts, quagga and bird are unnecessary.
3)If (question 1) is the right way to go then which of the ryu
application files do I need to change and run.
As mentioned above, please try application.py with its configuration
file, at first.
4)Do I need a config file for each peer?
Yes. You need to write configuration files for each peer.
5)Does BGP-4 in ryu support multicast bgp packet message
dissemination, if yes how can I accomplish this?
Currently, Ryu does not support advertising multicast routes.
Thanks,
Fujimoto

Hello Satoshi,
Here is a brief breakdown of what I am trying to do. My focus is on
message distribution in internal BGP (iBGP) so I want to
1)Create bgp peers
2)Establish bgp sessions between these peers
3)Send bgp packets through the network of bgp peers
4)My main objective is to manipulate how the bgp messages are
distributed and filtered in the simulated network
Since my experiment is more on the message distribution than network
changes, I think I can create a particular network with same bgp peers
while changing only the message dissemination rules.
At the end I would like to capture the number of messages per protocol
and the memory consumption in each of the peers.
My questions are:
1)Could this be accomplished using only ryu and mininet?
2)Do I need to integrate quagga or bird into this ryu application?
3)If (question 1) is the right way to go then which of the ryu

I tried running the sample conf file with:
ryu-manager ryu/services/protocols/bgp/application.py
--bgp-app-config-file ryu/services/protocols/bgp/bgp_sample_conf.py
but I got this error error
>>ryu-manager: error: unrecognized arguments: —bgp-app-config-file
ryu/services/protocols/bgp/bgp_sample_conf.py
When I remove the —bgp-app
ryu-manager ryu/services/protocols/bgp/application.py --config-file
ryu/services/protocols/bgp/bgp_sample_conf.py
I get:
>>raise ConfigFileParseError(pe.filename, str(pe))

However when I replace bgp_sample_conf.py with ryu.conf :
cd /home/ubuntu/ryu && ./bin/ryu-manager --verbose --config-file
~/ryu/etc/ryu/ryu.conf ~/ryu/ryu/services/protocols/bgp/application.py
I get:

Hi, Ukeme
Sorry, please let me make your problem more clear.
I understood as you want to implement a BGP app collaborating with
your OpenFlow app.
So, how will you make collaborating them?
For example, do you want to capture BGP packets and add neighbor
dynamically?
Please tell me in detail what do you want.
FYI, if you want a pure BGP application, the following code will be good.
https://github.com/osrg/ryu/blob/master/ryu/services/protocols/bgp/application.py
It works with its configuration file (the sample is
/ryu/services/protocols/bgp/bgp_sample_conf.py).
You can run it by this command:
ryu-manager ryu/services/protocols/bgp/application.py
--bgp-app-config-file ryu/services/protocols/bgp/bgp_sample_conf.py
Thanks,
Fujimoto

Hi.
I am new to using ryu and I am to implement bgp in ryu for my
project. I saw the sample bgpspeaker code on the Ryu doc site but I
don’t know how to go about implementing and running the application.
I need help with how to implement full mesh bgp using the ryu
bgpspeaker library and how to integrate it with my ryu application.
Thanks.
