Hi, Habib
Umm, I couldn't reproduce the issue you see...
More informations will be needed.
Could you give some informations like the followings?
* Your detailed network topology
(including whether your controllers and switches are in the same
host or not)
* Log message of Ryu with '--verbose' option
* Your bgp-app-config-files
Thanks,
Fujimoto

Hi Fujimot,
I checked the source and destinations on Open Message and they were
different. I put the full interaction between controllers before
crashing the peering here.

The last two interactions show the crash between controllers and in
controller CLI I have:
Sent notification to ('20.0.2.1', '45766') >>
BGPNotification(data='',error_code=6,error_subcode=7,len=21,type=3)
while on the other controller I have this error as below;
Sent notification to ('20.0.0.1', '179') >>
BGPNotification(data='',error_code=6,error_subcode=7,len=21,type=3)
These two interactions align with my settings.
Best regards,
Habib
