Description SCOPE OF WORK: Advanced SDN & Tenant Isolation (UDN/cUDN) Layer 3 Segmentation via OVN-Kubernetes: Implementing User Defined Networks (UDN) to support overlapping RFC1918 IP space across multiple sites while maintaining cryptographic or logical isolation. BGP Dynamic Routing via FRR-K8s: Configuring the FRR-K8s Operator to dynamically advertise UDN-specific routes to the physical Leaf/Spine fabric, specifically handling multi-hop BGP or complex prefix-filtering. Hardware Offloading: Tuning the CNI for high-performance edge workloads (e.g., SR-IOV or DPDK integration within a UDN). Nested OCP Environments (OCP on VMaaS) Recursive Virtualization Performance: Optimizing the KubeVirt/OpenShift Virtualization layer to host "Guest" OpenShift clusters with minimal latency overhead. Networking for Nested Clusters: Solving the "Double Overlay" problem-ensuring that the networking in the nested cluster can communicate efficiently with the physical network without triple-encapsulation penalties. Storage Pass-through: Configuring Dell PowerFlex CSI to provide persistent volumes through the virtualization layer to the nested K8s nodes while maintaining snapshot capabilities.
