In one embodiment, a method includes obtaining, at a first provider edge (PE) included a plurality of PEs multi-homed to a first customer edge (CE), traffic intended for the first CE, wherein the traffic includes a first indication, the first indication being configured to identify the traffic as flood traffic. A forwarding PE included in the plurality of PEs suitable to use to forward the traffic to the first CE is identified based on identifying traffic as the flood traffic. The method also includes determining whether the first PE is the forwarding PE, and providing the traffic to the first CE using the first PE when it is determined that the first PE is the forwarding PE. When it is determined that the first PE is not the forwarding PE, the traffic is filtered using the first PE.
