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: 

Enter system view

Configure the BS period 

c-bsr interval interval 

Optional 

For the default value, see the 
note below. 

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.
