1. Enter system view.
2. Enter public network PIM view
or VPN instance PIM view.
3. Configure the hash mask
length.
4. Configure the C-BSR priority.
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:
Step
1. Enter system view.
2. Enter public network PIM view
or VPN instance PIM view.
3. Configure the BS period.
4. Configure the BS timeout
timer.
NOTE:
If you configure the BS period or the BS timeout timer, the system uses the configured one instead of the
default one.

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.
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).
