◆ This command is used to enable IPv4 multicast routing globally for the
router. A specific multicast routing protocol also needs to be enabled on
the interfaces that will support multicast routing using the router pim
command, and then specify the interfaces that will support multicast
routing using the ip pim dense-mode or ip pim sparse-mode
commands.
◆ To use multicast routing, IGMP proxy can not enabled on any interface
of the device (see ip igmp proxy on page 1271 ).
