Abstract: In one embodiment, network node-to-node connectivity verification is performed in a network including data path processing of packets within a packet switching device. In one embodiment, an echo request connectivity test packet, emulating an echo request connectivity test packet received from a first connected network node, is inserted by the packet switching device prior in its data processing path prior to ingress processing performed for packets received from the first connected network node. A correspondingly received echo reply connectivity test packet is intercepted by the packet switching device during data path egress processing performed for packets to be forwarded to the first connected network node.

Abstract: A method may include bridging in, via a fabric, a multicast data packet from a source device to a first edge device of a plurality of edge devices and flooding the multicast data packet to the plurality of edge devices within a mutual subnetwork of the fabric. The method further includes bridging out the multicast data packet from a second edge device of the plurality of edge devices to a receiving device. The source device and the receiving device are located within the mutual subnetwork.
