Hey Yi,
Thanks for that information. I am sorry I did not make myself
clearer earlier. I do not see options to actually run two controllers
simultaneously, one as master and one as slave, as built in support for Ryu. If
I need that functionality, do I need to build that app myself?
For example, the comments on this link
http://comments.gmane.org/gmane.network.ryu.devel/901
<http://comments.gmane.org/gmane.network.ryu.devel/901> indicate that someone
built this app and that it is part of Ryu? Is that the case? Sending a role
change request happens if I have multiple controllers configured first,
correct? Please do correct me if I am wrong. I am looking for step 1 of how to
run multiple Ryu controllers talking to each other as Master/Slave or something
of that sort.
Thanks once again.
Regards,
Abhishek.
