Our network team tells me multicast is enabled within the switch. I had used ssmping to test multicast and it seemed to be working. I just ran it (ssmping) again, and if I start ssmpingd on node 1 and run ssmping from node 2 it works fine. If I start ssmpingd from node 2 and run ssmping from node 1 I get connection refused errors from ssmping.
