OpenShift cluster networking operates across two complementary layers: the DNS discovery layer (CoreDNS DaemonSet with deterministic 10th-address allocation and strict forwarding zone rules) and the multi-CNI data plane (OVN-Kubernetes primary + Multus secondary with NAD-based pod attachment) — both must be healthy for workloads to communicate.
depth-2 — discovery and data plane are independently architected but jointly required for connectivity
Depends on (SL): dns-service-discovery-architecture, multi-cni-network-architecture
