Node configuration

Node configuration

For all Neutron OVS use cases, configure four VLANs and four IP addresses in separate networks on all compute and network nodes. You will also need two VLAN ranges for tenant traffic and external VLAN traffic.

The following table describes a node network configuration for a Neutron OVS-based MCP OpenStack cluster:

Depending on hardware capabilities, you can separate bonds for the control plane and data plane.

Depending on your use case, configure your network nodes to use the VLAN or VXLAN-based tenant network.
