Network requirement of node connectivity in OCP3

Solution Verified - Updated -

Issue

  • When deploy a new OpenShift cluster, where the install completed but left the standalone node without connectivity. "oc get nodes" all confirmed that the node was not active or even add. Do all nodes added to a cluster have to be in the same network/subnet? Are there any requirements for the connection between nodes?

Environment

  • OpenShift Container Platform 3+
