By default, no IPv6 BIDIR-PIM
domain border is configured.
Configuring the global C-BSR parameters
In each IPv6 BIDIR-PIM domain, a unique BSR is elected from C-BSRs. The C-RPs in the IPv6
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 IPv6 BIDIR-PIM
domain. All the routers use the same hash algorithm to get the RP address corresponding to specific
multicast groups.
Perform the following configuration on C-BSR routers.

Optional.
64 by default.
Configuring C-BSR timers
The BSR election winner multicasts its own IPv6 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 BS (BSR state) 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. If you configure value for the C-BSR timers,
the system uses the configured ones instead of the default ones.

3.
Configure the BS period.
c-bsr interval
interval
Optional.
By default, the BS period is
determined by the formula "BS
period = (BS timeout timer – 10) /
2." The default BS timeout timer is
130 seconds, so the default BS
period is (130 – 10) / 2 = 60
(seconds).
