Command Mode
Privileged EXEC
Usage
This command helps discover whether the IGMP processes are functioning. In general, if IGMP is not
working, the process never discovers that another host is on the network that is configured to receive
multicast packets. In sparse mode, packets will never be delivered.
Use this command in conjunction with the debug pim commands to observe additional multicast activity
