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:
root@mininet-vm:~# ryu-manager --verbose --config-file
/home/mininet/ryubgp/ryu.conf
/home/mininet/ryu/ryu/services/protocols/bgp/application.py
* OUTPUT:*
loading app /home/mininet/ryu/ryu/services/protocols/bgp/application.py
Create CustomEvent called
instantiating app
/home/mininet/ryu/ryu/services/protocols/bgp/application.py of RyuBGPSpeaker
BRICK RyuBGPSpeaker
NetworkController started listening for connections...
Error creating socket: [Errno 97] Address family not supported by
protocol
Pls advice
Thanks
Hadem
