Abstract: A networking apparatus includes a communication circuitry configured to receive, via first control message data units (CMDUs), network information descriptive of links between network devices of a network. The networking apparatus also includes a processor configured to determine, based on the network information, an end-to-end routing path for unicast communications from the communication circuitry to a second network device of the network, where the end-to-end routing path traverses a first network device of the network. The processor is further configured to cause the communication circuitry to send, to the first network device via one or more second CMDUs, routing path information descriptive of at least a portion of the end-to-end routing path. The routing path information is configured to cause the first network device to forward, along the portion of the end-to-end routing path, unicast packets received from the communication circuitry and addressed to the second network device.
