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 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 takes place. If the BSR state times out and no bootstrap message is received from the
BSR, a new BSR election process is triggered among the C-BSRs.
Perform the following configuration on C-BSR routers.
Follow these steps to configure C-BSR timers:

About the BS period:
z By default, the BS period is determined by this formula: BS period = (BS timeout – 10) / 2.
The default BS timeout is 130 seconds, so the default BS period = (130 – 10) / 2 = 60
(seconds).
z If this parameter is manually configured, the system will use the configured value.
About the BS timeout:
z By default, the BS timeout value is determined by this formula: BS timeout = BS period × 2
+ 10. The default BS period is 60 seconds, so the default BS timeout = 60 × 2 + 10 = 130
(seconds).
z If this parameter is manually configured, the system will use the configured value.
