OpenStack Caracal : Configure Neutron OVN (Network Node)2024/08/07 |
|
Configure OpenStack Network Service (Neutron).
This example is based on the environment like follows.
------------+--------------------------+--------------------------+------------

eth0|10.0.0.30 eth0|10.0.0.50 eth0|10.0.0.51
+-----------+-----------+ +-----------+-----------+ +-----------+-----------+
| [ dlp.srv.world ] | | [ network.srv.world ] | | [ node01.srv.world ] |
| (Control Node) | | (Network Node) | | (Compute Node) |
| | | | | |
| MariaDB RabbitMQ | | Open vSwitch | | Libvirt |
| Memcached Nginx | | Neutron Server | | Nova Compute |
| Keystone httpd | | OVN-Northd | | Open vSwitch |
| Glance Nova API | | Nginx | | OVN Metadata Agent |
