I'm not sure we're using "interface" the same way. I have two interfaces on my system: eth0 and eth1. I want iperf to join a multicast group (e.g., 224.0.12.34) and to send its IGMP Report out eth1. If I specify the IP address of my local host on eth1 as the value of -B, where do I specify the multicast group?
