I have set values to the *ECN* field of IPv4 packet Header at the *ingress

I want to run the RYU BGP

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

Hi Guys,
I am presently testing the SDX-RYU project.
https://github.com/sdn-ixp/sdx-ryu/tree/master/
Can some expert here confirm whether BGP update messages are being sent
from QuaggaHosts a1, b1 etc... to the Route Server?
If so, can you you shed some light on this?
Thanks in advance.
Regards
Hadem

Hi,
Is there an implementation of a REST API-based inter-controller
communication in Ryu?.
If so, kindly share necessary information.
Thanks
