ES4710BD 10 Slots L2/L3/L4 Chassis Switch

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
