ip igmp join-group x.x.x.x
I thought that applying "ip igmp join-group 188.8.131.52"
makes the interface under which is executed a member of 184.108.40.206 for
as long as the command is there. The problem is that the switch (in this
case ME3400) never sends another IGMP report and the multicast stream
gets pruned. I guess it is a bug?
