Configuring global C-BSR parameters
In each BIDIR-PIM domain, a unique BSR is elected from C-BSRs. The C-RPs in the BIDIR-PIM domain send
advertisement messages to the BSR. The BSR summarizes the advertisement messages to form an RP-set
and advertises it to all routers in the BIDIR-PIM domain. All the routers use the same hash algorithm to get
the RP address corresponding to specific multicast groups.
The following rules apply to the hash mask length and C-BSR priority:
• You configure the hash mask length and C-BSR priority globally, in an admin-scoped zone, and in
the global scope zone.
• The values configured in the global scope zone or admin-scoped zone have preference over the
global values.
• If you do not configure these parameters in the global scope zone or admin-scoped zone, the
corresponding global values will be used.
For configuration of C-BSR parameters for an admin-scoped zone and global scope zone, see
"Configuring C-BSRs for each admin-scoped zone and the global-scoped zone."
Perform the following configuration on C-BSR routers.

Configuring C-BSR timers
The BSR election winner multicasts its own IP address and RP-Set information through bootstrap messages
within the entire zone it serves. The BSR floods bootstrap messages throughout the network at the interval
of the BS period.
Any C-BSR that receives a bootstrap message retains the RP-set for the length of BS timeout timer, during
which no BSR election takes place. If no bootstrap message is received from the BSR when the BS timeout
timer expires, a new BSR election process is triggered among the C-BSRs.
Perform the following configuration on C-BSR routers.
