Hi Takeshi,
I am following the below steps:
1) sudo python as.py ---> runs successfully
2) On a new terminal: sudo mininet/util m r1 ---> Gives me a new prompt but
not sure if i am in a new separate namespace. Pls confirm if this is the
correct way
3) On a new terminal: sudo mininet/util m r2 ---> Gives me a new prompt but
not sure if i am in a new separate namespace. Pls confirm if this is the
correct way
4) I executed the following on the supposedly r1 and r2 terminals:
r1(supposedly): sudo ryu-manager
ryu/services/protocols/bgp/application.py --bgp-app-config-file
bgpconfig1.py
r2(supposedly): sudo ryu-manager
ryu/services/protocols/bgp/application.py --bgp-app-config-file
bgpconfig2.py
However I am getting the following errors on both the supposedly r1 and r2
terminal.
-------------------------------------------------------
Error creating socket: [Errno 98] Address already in use
hub: uncaught exception: Traceback (most recent call last):
File "/usr/local/lib/python2.7/dist-packages/ryu/lib/hub.py", line 59, in

-----------------------------------------------------
Pls Guide. Am i doing something wrongly?.
I am also attaching the two config files( bgpconfig1.py & bgpconfig2.py)
Thanks
