Abstract
Methods, systems, and apparatus, including computer programs encoded on a storage media, for preventing looping and duplicate frame delivery in a network environment. A first control plane message is received from a first edge node in a plurality of edge nodes in a plurality of network elements of a network, the first control plane message identifying a first hint to be included in first multicast packets that include data originating from a first computing device interfaced with the first edge node and are forwarded to the network through the first edge node. A data record is stored identifying the association between the first hint and the first computing device. The data record is used to determine that multicast packets including the first hint originate from the first computing device and are not to be forwarded to the first computing device by edge nodes interfacing with the first computing device.
