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 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.
To configure C-BSR timers:

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).
The BS period value must be
smaller than the BS timeout timer.
4. Configure the BS timeout
timer.
c-bsr holdtime interval
Optional.
By default, the BS timeout timer is
determined by the formula "BS
timeout timer = BS period × 2 +
10." The default BS period is 60
seconds, so the default BS timeout
timer = 60 × 2 + 10 = 130
(seconds).
NOTE:
If you configure the BS period or the BS timeout timer, the system uses the configured one instead of the
default one.
