Router enable "ip multicast-routing" and CGMP/IGMP and ip pim sparse-dense-mode on the ports that will be forwarding traffic for multicast. On the switch enable the same thing on the VLAN interfaces. Also enable global igmp or cgmp.
what is CGMP/IGMP? Is it the routing protocol? By the way, can give me the example of coding for setting up the CGMP/IGMP?
