Nowadays, the n-d-r service architecture depends of some kind of messaging between the DRAgent service and Neutron server side. However, this communications is strongly depent of the messaging service availability (RabbitMQ by default), and any transient/permanent failures in openstack infrastructure nodes may affect prefix advertising via BGP.
The issue here is not related to communication dependent on the messaging service itself, as this is the common design of OpenStack modules. I'm talking about how the control plane service (n-d-r) can actively affect the data plane.
I understand that the application design drop BGP peer connection after a certain timeout without RMQ communication (in my tests it took 1 hour) but as a result, all the prefixes/FIPs will stop to advertising (dropping the external connectivity). To be clear, lack of messages between the Neutron server and DRAgent via RMQ will cause a general unavailability of the whole North/South data plane.
IMO: it would be helpfully for the DRAgent service to implement a resilience solution for the data plane, keeping sessions with BGP peers and waiting for te RMQ communication back (A large timeout can be help here). Additionally, the n-d-r on the Neutron side needs to keep the bgp speaker alive in infrastructure failure cases because if the speaker is removed the DRAgent will no longer work.
I know that RMQ being out of servive for long periods is critical for many parts of OpenStack, but even with HA in the DRAgents depoloyment, we will have a single point of failure, as n-d-r agent needs to communicate with Neutron via the messaging service.
Has anyone else had this problem? Does it make sense to you?
