OpenStack Ocata : Configure Neutron#22017/03/12 |
|
Configure OpenStack Network Service (Neutron).
This example is based on the emvironment like follows.
If you'd like to install Neutron services on another Computer, refer to here.
Neutron needs a plugin software, it's possible to choose it from some softwares.
This example chooses ML2 plugin. ( it uses LinuxBridge under the backend )
eth0|10.0.0.30
