Crossing the border - VM goes on a BGP adventure
summary
OVN-Kubernetes now ships user-defined networks and BGP via FRR, using FR Kubernetes CRDs (FRConfiguration and route-advertise) to import and advertise routes so VMs and provider networks exchange prefixes directly. The demo wiring binds a per-UDN VRF device to eno4 to stretch a UDN across clusters with VRF-lite, yielding fully routed VM-to-VM and VM-to-provider paths (no NAT/gateway) with lower latency and higher throughput; EVPN support is planned to remove the manual VRF wiring.
