Configuring C-BSR parameters globally
In each IPv6 PIM-SM domain, a unique BSR is elected from C-BSRs. The C-RPs in the IPv6 PIM-SM
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 IPv6 PIM-SM domain. All the routers use the same
hash algorithm to get the RP address that corresponds to specific IPv6 multicast groups.
Perform the following configuration on C-BSR routers.
Follow these steps to configure C-BSR parameters globally:

Configuring C-BSR timers
The BSR election winner multicasts its own IPv6 address and RP-set information throughout the region that
it serves through bootstrap messages. The BSR floods bootstrap messages throughout the network at the
interval of the BS (BSR state) period. Any C-BSR that receives a bootstrap message retains the RP-set for
the length of BS timeout, during which no BSR election occurs. If no bootstrap message is received from
the BSR before the BS timeout timer expires, a new BSR election process begins among the C-BSRs.
Perform the following configuration on C-BSR routers.
