1	Confirm that this system is a candidate for BSR.	If this system is not a candidate for BSR, check the
	show ipv6 pim bsr	configuration and set the configuration to run this system as a
		candidate for BSR. Since this system does not run as a
		candidate for BSR if no address is set for the loopback
		interface, confirm that an address is set for the loopback
		interface.
2	Confirm that this system is BSR.	If this system is not BSR, check the priority of other BSR
	show ipv6 pim bsr	candidates. The larger the value, the higher the priority. If the
		same priority is provided, the BSR candidate with the largest
		BSR address becomes BSR.

(3) Rendezvous point router check items

The table below shows the items to be checked when this system is the rendezvous point router in the IPv6 PIM-SM network configuration.

		rendezvous point is distributed for each group address
		according to the protocol specifications and this system may
		not run as the rendezvous point. To run this system
		preferentially as the rendezvous point, set the priority higher
		than those of other rendezvous point candidates.

(4) last-hop-router check items

The table below shows the items to be checked when this system is the last-hop-router in the IPv6 PIM-SM network configuration.
