On receiving BSR advertised C-RP messages, multicast routers will calculate the RP corresponding to a certain multicast group with the same algorithm.

It should be noted that one RP can service multiple multicast groups or all multicast groups. Each multicast group in any time can have only one corresponding RP, multiple associations is forbidden. 2) Configure BSR

BSR is the core of management in PIM-SM networks; it is responsible for gathering information from C-RP and broadcasting the information gathered.

Each network can have one BSR, and several Candidate-BSRs (C-BSRs). This way, once a BSR fails, another BSR will quickly take its place. BSR will be decided by the auto-election between C-BSRs.

19.4.2.1PIM-SM Configuration Task Sequence

1. Enable PIM-SM protocol

Basic configuration of PIM-SM routing protocol on ES4710BD series switches is quite simple: just enable PIM-SM in the appropriate interfaces.

Command	Explanation
Interface Mode
ip pim sparse-mode	Enable PIM-SM protocol; the “no ip pim sparse-mode” command
no ip pim sparse-mode	disables PIM-SM protocol (required)

2. Configure PIM-SM sub-parameters

1)Configure PIM-SM interface parameters

1)Configure PIM-SM HELLO packet interval

Command	Explanation
Interface Mode
ip pim query-interval <query	Sets interval for sending PIM-SM HELLO packets
interval>	in the interface; the “no ip pim query-interval”
no ip pim query-interval	command restores the default setting.

2)Configure the interface as the PIM-SM BSR border

	Command	Explanation
	Interface Mode
	ip pim bsr-border	Sets the interface as the PIM-SM BSR border; the
		“no ip pim bsr-border” command cancels the
	no ip pim bsr-border
		setting of BSR border.
2) Configure PIM-SM global parameters
