OpenStack Rocky : Configure Neutron Network (VXLAN)
2018/09/17
 
Configure virtual networking by OpenStack Network Service (Neutron).
For example, configure VXLAN type of networking on here.
Before it, Configure basic settings on Control Node, Network Node, Compute Node.
Furthermore, this example is based on the environment that Network Node has 2 network interfaces.
And also eth1 is up without IP Address, refer to here of [1] to up anonymous interface on Netplan.
