I tried the client connection with only the multicast helper on Vlan1
and it didn't work. I added the other multicast helper to Vlan4 and the
6513 rebooted.  :-)  That's not a good thing to have happen during the
day! Really bad idea on my part. Luckily, I have a redundant Sup in RPR+
mode so it wasn't down long, but it was down long enough to irritate a
whole bunch of people.

Back to the drawing board...
