20.(Optional) The checksum of the PIM register messages is calculated without including the multicast payload. Earlier releases of the Cisco IOS calculate the checksum by including the multicast payload. If you experience difficulties having PIM register messages sent by the Nokia appliance being accepted by a Cisco router that is the elected rendezvous point (RP), configure this option. A Nokia appliance that is the elected RP accepts register messages that calculate the checksum with or without the multicast payload, that is, it accepts all register messages.

	This command also displays the interface and its DR priority and the number of
	PIM neighbors on the interface.
show pim neighbors	The IP address of each PIM neighbor and the interface on which the neighbor is
	present. This command also displays the neighbor’s DR priority, generation ID,
	holdtime and the time the neighbor is set to expire based on the holdtime
	received in the most recent hello message.
show pim statistics	The number of different types of PIM packets received and transmitted and any
	associated errors.
show mfc cache	Multicast source and group forwarding state by prefix.
show mfc interfaces	Shows multicast source and group forwarding state by interface.

The following iclid commands can assist you in debugging sparse-mode PIM (PIM-SM):

Command	Shows
show pim bootstrap	The IP address and state of the Bootstrap router.
show pim candidate-rp	The state of the Candidate Rendezvous Point state machine.
