The BGP dynamic routing plugin was first introduced in the Mitaka release of OpenStack Networking and supports the native L3 agent provided by Neutron.
To install the BGP service plugin, modify the Neutron configuration file on the controller node hosting the Neutron API service. In this environment, API services are running on controller01. Add the BGP plugin to the list of existing service plugins as shown here:
[DEFAULT]
...
service_plugins = router,
neutron_lbaas.services.loadbalancer.plugin.LoadBalancerPluginv2,
trunk,neutron_dynamic_routing.services.bgp.bgp_plugin.BgpPlugin
Be sure to append to the existing list of plugins, rather than replacing the list contents, to avoid issues with the API and existing network objects.
