Abstract:
A first multicast data packet can be received by a particular edge node, forwarded from another network element in a network, the first packet including data received from a particular device interfacing with the network through a first edge node. The first packet is multicast by the first edge node. The particular edge node is included in a redundancy group including at least one other edge node. The first multicast data packet is examined to identify a first hint corresponding to the particular device. In response to identifying the particular device, it is determined that the particular edge node does not interface with the particular device. It is further determined that the particular edge node is designated as a forwarding node for the redundancy group. Based on these determinations, the first packet is forwarded by the particular edge node while preventing looping and duplicate packet delivery.
