Patent ID: 11855804

Abstract:
A network device serving as a local VXLAN) Tunnel Endpoint (VTEP) includes a communication interface, a first processor and a packet processor. The communication interface communicates between the local VTEP and remote VTEPs, each VTEP has a respective VXLAN Identifier (VNI). The first processor imports a Downstream-VNI (D-VNI) to be used in forwarding packets from the local VTEP to a remote VTEP, creates a unique egress Routing Interface (RIF) that is translatable into the imported D-VNI, and associates the unique egress RIF with one or more route entries in the local VTEP. The packet processor receives a packet destined to the remote VTEP, looks up the packet in the route entries in the local VTEP to retrieve the unique egress RIF, translates the unique egress RIF into the imported D-VNI, encapsulates the packet with the imported D-VNI, and forwards the encapsulated packet in accordance with the unique egress RIF.
