A source device on a first Layer 2 site transmits a frame to a destination device on the same subnet, but on a second Layer 2 site. The frame is encapsulated and routed to a fabric border node. The fabric border node matches the source subnet to the destination subnet and transmits an address request protocol (“ARP”). In response to not receiving a reply to the ARP, the fabric border node transmits a map request to a Layer 3 transit fabric control plane node. The control plane node extracts a destination identifier from the map request and determines that the destination identifier is a Layer 2 identifier. The control plane node transmits a map reply to the fabric border node, where the frame is re-encapsulated and forwarded to the destination device."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Normalized lookup and forwarding for diverse virtual private networks","description":"This technology enables normalized lookup and forwarding for diverse virtual private networks in multi-site network fabric deployments.
