OpenShift networking is a unified three-layer architecture: DNS discovery (CoreDNS DaemonSet with deterministic IP allocation), multi-CNI data plane (OVN-Kubernetes + Multus for secondary interfaces), and dual-stack IPv4/IPv6 addressing — where the addressing layer imposes platform-specific constraints back onto the data plane.
Both depth-2 nodes share multi-CNI architecture as foundation but capture orthogonal concerns (discovery+data vs addressing+constraints); combining reveals that addressing constraints propagate back to restrict data plane options
