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:

Configure the BS timeout
c-bsr holdtime interval
Optional
For the default value, see the note below.
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.
In configuration, make sure that the BS period is smaller than the BS timeout value.
Configuring IPv6 Multicast Source Registration
Within an IPv6 PIM-SM domain, the source-side DR sends register messages to the RP, and these
register messages have different IPv6 multicast source or IPv6 multicast group addresses. You can
configure a filtering rule to filter register messages so that the RP can serve specific IPv6 multicast
groups. If an (S, G) entry is denied by the filtering rule, or the action for this entry is not defined in the
filtering rule, the RP will send a register-stop message to the DR to stop the registration process for the
IPv6 multicast data.
