Public bug reported: ## Description
We run OpenStack Ussuri and see the following errors repeatedly on `neutron-server.log`: ``` 2021-04-14 16:39:02.230 30704 ERROR neutron_lib.callbacks.manager [req-33c1014f-75c4-4306-96a8-927bb62f7f60 1718caa43bf24e7990cc09d5daa1fb85 46e94ce6568449209de022fa3bbbbae4 - 3dbb1c3c0fc54cc0b793ac49f841f103 3dbb1c3c0fc54cc0b793ac49f841f103] Error during notification for neutron_dynamic_routing.services.bgp.bgp_plugin.BgpPlugin.floatingip_update_callback--9223372036854663447 floatingip, after_update: TypeError: unsupported operand type(s) for +: 'int' and 'str' 2021-04-14 16:39:02.230 30704 ERROR neutron_lib.callbacks.manager Traceback (most recent call last): 2021-04-14 16:39:02.230 30704 ERROR neutron_lib.callbacks.manager File "/usr/lib/python3/dist-packages/neutron_lib/callbacks/manager.py", line 197, in _notify_loop 2021-04-14 16:39:02.230 30704 ERROR neutron_lib.callbacks.manager callback(resource, event, trigger, **kwargs) 2021-04-14 16:39:02.230 30704 ERROR neutron_lib.callbacks.manager File "/usr/lib/python3/dist-packages/neutron_dynamic_routing/services/bgp/bgp_plugin.py", line 235, in floatingip_update_callback 2021-04-14 16:39:02.230 30704 ERROR neutron_lib.callbacks.manager dest = floating_ip_address + '/32' 2021-04-14 16:39:02.230 30704 ERROR neutron_lib.callbacks.manager File "/usr/lib/python3/dist-packages/netaddr/ip/__init__.py", line 426, in __add__ 2021-04-14 16:39:02.230 30704 ERROR neutron_lib.callbacks.manager new_value = int(self._value + num) 2021-04-14 16:39:02.230 30704 ERROR neutron_lib.callbacks.manager TypeError: unsupported operand type(s) for +: 'int' and 'str' ``` The error is caused by https://opendev.org/openstack/neutron-dynamic- routing/src/branch/master/neutron_dynamic_routing/services/bgp/bgp_plugin.py#L235.
