PIM Candidate BSR Settings
The following windows are used to configure the Candidate Boot Strap Router (C-BSR) settings for the switch and the priority of
the selected IP interface to become the Boot Strap Router (BSR) for the PIM enabled network. The Boot Strap Router holds the
information which determines which router on the network is to be elected as the RP for the multicast group and then to gather
and distribute RP information to other PIM-SM enabled routers. To view the Candidate BSR window, click Configuration >
Layer 3 IP Networking > IP Multicast Routing Protocol > PIM Protocol > PIM Candidate BSR Settings.

Parameter Description
C-BSR Hash Mask Len
(0-255)
Enter a hash mask length, which will be used with the IP address of the candidate RP and
the multicast group address, to calculate the hash algorithm used by the router to
determine which C-RP on the PIM-SM enabled network will be the RP. The user may
select a length between 0 –32 with a default setting of 30.
C-BSR Bootstrap
Period (0-255)
Enter a time period between 1-255 to determine the interval, the Switch will send out Boot
Strap Messages (BSM) to the PIM enabled network. The default setting is 60 seconds.
