Requirements for Multus configuration

• The interface used for the public network must have the same interface name on each OpenShift storage and worker node, and the interfaces must all be connected to the same underlying network.

• The interface used for the cluster network must have the same interface name on each OpenShift storage node, and all the interfaces must be connected to the same underlying network. Cluster network interfaces do not have to be present on the OpenShift worker nodes.

• Each network interface used for the public or cluster network must be capable of at least 10 gigabit network speeds.

• Each network requires a separate virtual local area network (VLAN) or subnet.
