Hi Takeshi,
*I am now running the complete environment in Ubuntu 16.04. However i am
still getting the below error:*
*root@ubuntu:~/ryu# ryu-manager ryu/services/protocols/bgp/application.py
--bgp-app-config-file bgpconfig1.py*
*loading app ryu/services/protocols/bgp/application.py*
*instantiating app ryu/services/protocols/bgp/application.py of
RyuBGPSpeaker*
*API method core.start called with args: {'router_id': '10.0.0.1',

*Error creating socket: [Errno 98] Address already in use*
*I have issued the killall comand as below:*
*root@ubuntu:~/ryu# sudo killall quagga*
*quagga: no process found*
Pls Guide. Can you share your Quagga Installation/Configuration Steps?.
That would clarify several doubts.
It would really be helpful if you can run the BGP applications on r1 and r2
and see the result.
Thanks
Hadem
