OpenStack Zed : Configure Neutron #22023/06/27 |
|
Configure OpenStack Network Service (Neutron).
This example is based on the environment like follows.
If you'd like to install Neutron services on another Host, refer to here.
Neutron needs a plugin software, it's possible to choose it from some softwares.
This example chooses ML2 plugin. ( it uses Open vSwitch under the backend )
eth0|10.0.0.30
+-----------+-----------+
| [ dlp.srv.world ] |
| (Control Node) |

| MariaDB RabbitMQ |
| Memcached Nginx |
| Keystone httpd |
| Glance Nova API |
| Nova Compute |
| Neutron Server |
| Neutron Metadata |
| Neutron L2/L3 Agent |
| Open vSwitch |
