Lab Description
Very basic PIM-BiDir lab. R4 is an RP placed at the top of the topology. There is one source and two hosts. Both hosts have joined the multicast group 228.1.1.9 using the ip igmp join-group 228.1.1.9 sub-interface command. Start multicast traffic by implementing a constant ping from the source device to 228.1.1.9.
