Agent

Neutron-dynamic-routing implements a new agent named "DRAgent". The agent talks to the neutron-dynamic-routing plugin which resides in the neutron server to get routing entity configuration. DRAgent interacts with the back-end driver to realize the required dynamic routing protocol functionality. For details, please refer to the system design document system-design

Note

One DRAgent can support multiple drivers but currently ONLY Ryu is integrated successfully.

Scheduler

Neutron-dynamic-routing scheduler, schedules a routing entity to a proper DRAgent.

BGP Scheduler

BGP Speaker and DRAgent has 1:N association which means one BGP speaker can be scheduled on multiple DRAgents.

Here is an example to associate/disassociate a BGP Speaker to/from a DRAgent.
