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
application files do I need to change and run.
4)Do I need a config file for each peer?
5)Does BGP-4 in ryu support multicast bgp packet message dissemination,
if yes how can I accomplish this?
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))
oslo_config.cfg.ConfigFileParseError: Failed to parse

/home/ubuntu/ryu/ryu/services/protocols/bgp/bgp_sample_conf.py:1, No ':' or '='

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:

I am using the sdn hub vm ubuntu 64 from

Thanks.
