Hi, Pynbiang
I'm sorry for that I've overlooked your reply.
I think something may be wrong with your ryu.conf, especially about IP
address or port settings.
Please check your ryu.conf, or could you let me see your ryu.conf?
Thanks,
Fujimoto

Hi Fujimoto,
I have followed the steps given by you:
1)$ sudo mn --switch ovsbr --topo single,2 --mac -x
2) in host1 (xterm) i executed the following:

Hi,
I'm running the above BGP test applications on ryu 3.30 and am
getting some errors:
File"/usr/local/lib/python2.7/dist-packages/eventlet/greenio/base.py",
line46,in socket_checkerr
raise socket.error(err, errno.errorcode[err])
error: [Errno101] ENETUNREACH
I executed as below:
ryu-manager /home/mininet/BGP3/application1.py --config-file
/home/mininet/BGP3/ryu.conf
Do i need to run it on higher version of ryu?. Pls advice
Thanks

Hi, Pynbiang
FYI, you can run two Ryu BGP applications by the following
steps:
1. Run mininet
$ sudo mn --switch ovsbr --topo single,2 --mac -x
2. Run applications in each host
h1> ryu-manager [application1.py]
--bgp-app-config-file [config_file_for_application1.py]
h2> ryu-manager [application2.py]
--bgp-app-config-file [config_file_for_application2.py]
Thanks,
Fujimoto

Hi, Pynbiang
I guess it is the cause of the problem that the two
applications use the same port.
Unfortunately, the port which the application uses is no
configurable,
so you cannot run the two applications simultaneously in
a single host.
To run the applications, I suggest the following choices.
1. I recommend you to use Docker or VM(Virtual Box, KVM,
...).
You can run applications in each container or VM.
2. If you have installed mininet, you can run
applications in each virtual host("h1", "h2", ...)
created by mininet.
It is because the namespace is separated by virtual
hosts.
Please note that virtual switches such as "s1" is
not in a separated namespace,
so you have to run applications in virtual hosts.

Fujimoto

Hi,
I prepared two instances of the RYU BGP app as below:
1) /home/mininet/BGP1/application1.py
2) /home/mininet/BGP2/application2.py
I also made the changes to the application1.py
(correspondingly for application2.py) as below:
CONF.register_opts([
cfg.IntOpt('bind-port',default=50001,help='rpc-port'),
cfg.StrOpt('bind-ip',default='0.0.0.1',help='rpc-bind-ip'),
cfg.StrOpt('bgp-config-file',default="/home/mininet/BGP1/bgpconfig1.py",
help='bgp-config-file')
])
I am also attaching herewith the modified*configuration files*
taken from ryu/ryu/services/protocols/bgp_sample_conf.py for application1.py
and application2.py respectively.
The problem is that i am not able to run the two applications
simultaneously.
Kindly advice what else i am missing here.
Thanks

Hi, Pynbiang. Yes, you need to run at least 3
instances of the application for a network with
three AS. If you want to run more BGP instances in
an AS, you need to run more instances of the
application. Thanks, Fujimoto

Pls advice. I am not able to proceed with the test.
