Abstract
One embodiment includes a network device including multiple interfaces to serve as ingress ports for receiving network packets from nodes in remote customer-site network(s) via a tunnel in a provider network, and from nodes in a local customer-site network, and egress ports for forwarding at least some of the network packets, and control circuitry to make a decision to drop a network packet to reduce packet duplication in at least one of the nodes, responsively to the network packet being identified as a packet of broadcast, unknown unicast, or multicast traffic, the network packet being subject to decapsulation of an encapsulation header, being assigned to one of the egress ports, and having a header including one of a plurality of virtual local area network identifications, or one of a plurality of source identifications.
