IP Multicast

   Bear with me, I've got a couple of multicast questions:
   I want to configure IP Multicast such that a multicast server on
   R1's E0 intf can send multicast packets to receivers on R2's and R3's
   lan interfaces.
   How can you test it? Can you do an "ip igmp join 224.100.100.100"
   on each lan interface and ping that address to test it?
   I am assuming that testing PIM Sparse-Mode is a similar test?
   Does the To0 interface affect anything in the config?
   What's the difference between configuring PIM-Dense and just running a
   multicast routing protocol like OSPF on every router and doing an "ip
   igmp join 224.X.X.X" on each interface?
   I have a Multicast PIM Dense Mode config as follows:
   |-R1---R2---R3-O
   PIM-DM Example
   R1#
   ip muticast-routing
   int e0
    ip pim dense-mode
   int s0
    ip pim dense-mode
   R2#
   ip multicast-routing
   int s0
    ip pim dense-mode
   int s1
    ip pim dense-mode
   R3#
   ip multicast-routing
   nit s0
    ip pim dense-mode
   int to0
    ip pim dense-mode
   Thanks,
   Ben
