I just kind of assumed, maybe it was a bad assumption? I assumed because I
was able to ping the mcast group IP and get a reply when pinging from both
R8 and SW4, just not from R7 across the frame cloud. Other traffic across
the cloud was passing fine... No, I didn't try putting the join group on R8,
the task specified that it needed to be on SW4... I could lab this up again
and give it a shot...
Thanks,
Chris
