Example interfaces and connections

Example interfaces and connections illustrate how different node types can be configured for Multus networking.

The following diagram shows example interfaces and connections that might be planned for each node type:

This example includes cluster network for completeness.

In this example, vlan220 (public) and vlan221 (cluster) are the interfaces to use for Fusion Data Foundation configuration. If VLANs are unused in the deployed environment, bond1 and bond2 would be used instead. If no bonds or VLANs are used, host interfaces (for example, eth2, eth4) would be used instead. When using Whereabouts IPAM, IP addresses are not required on Multus parent interfaces such as NICs, bonds, or VLANs (for example, eth2–eth4, bond1–bond2, vlan220–vlan221).

Important: The "ODF public network" in the diagram accounts for both the Fusion Data Foundation Pod public network and Fusion Data Foundation node public network. The OpenShift machine network is used as a backbone for the OpenShift Pod network and is included for reference only. Do not mistake this network for the ODF node public network. Do not plan or execute routing that involves the machine network.
