EES4710BD 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.
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
no ip pim sparse-mode
Enable PIM-SM protocol; the “no ip pim sparse-mode” command
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
interval>
no ip pim query-interval
Sets interval for sending PIM-SM HELLO packets
in the interface; the “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
no ip pim bsr-border
Sets the interface as the PIM-SM BSR border; the
“no ip pim bsr-border” command cancels the
setting of BSR border.
2) Configure PIM-SM global parameters
