1. A switch, comprising:

  • a processor;

    a storage device coupled to the processor and storing instructions which when executed by the processor cause the processor to perform a method, the method comprising;

    generating a virtual routing node identifier for a non-routing node, wherein the virtual routing node identifier indicates a multi-switch link aggregation;

    constructing a frame comprising reachability information corresponding to the virtual routing node identifier;

    marking an ingress-node field of a frame received from the non-routing node with the virtual routing node identifier; and

    precluding a received multi-destination frame from being forwarded to the non-routing node when an ingress-node field of the multi-destination frame matches the virtual routing node identifier, thereby avoiding duplication of the multi-destination frame.
