    Abstract: A technique implements forwarding operation shortcuts at a switch for multicast data traffic routed between subnetworks of a computer network. A first multicast frame is forwarded from the switch to a router, which peforms route processing and forwarding operations for a packet encapsulated within the frame. During execution of the operations, the router provides multicast flow and additional information concerning the routed packet to the switch in accordance with a novel multicast shortcut control protocol. The information is used by the switch to implement a novel multicast shortcut for subsequent frames received at the switch having the multicast packet flow.

    Abstract: A technique enables learning and switching of frames between line cards that are interconnected by a switch fabric of a distributed network switch. The network switch comprises a router and a plurality of forwarding engines, each having an associated forwarding table. The distributed learning and switching technique configures (i) the router to issue an extra copy of a routed frame to an ingress card having a port attached to the source of the frame; (ii) the router to ensure that the contents of a source index field of the routed frame header indicate that the frame originated from the ingress card; (iii) the router to assert a shortcut bit in the header of the routed frame; (iv) a forwarding engine on an egress card having a port attached to the destination of the frame to generate and issue a media access control notification frame to the ingress card and (v) a forwarding engine on the ingress card to mark an established entry in a layer 2 (L2) portion of its forwarding table as ineligible for normal L2 aging policies.
