To do...
3. Configure the hash mask
length.
4. Configure the C-BSR priority.
Hash mask length and C-BSR priority
You can configure these parameters at three levels:
• Global configuration level
• Global scope zone level
Admin-scope zone level
•
Parameter values configured at the global scope zone level or admin-scope zone level have preference
over the global configuration level values, and default to the global value level.
For configuration of C-BSR parameters for an admin-scope zone and global scope zone, see
"Configuring C-BSRs for each admin-scope zone and the global-scope
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, 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.
To do...
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.
BS period and timeout settings
Make sure that the BS period value is smaller than the BS timeout value.
The BS period defaults to the value determined by the formula:
"BS period = (BS timeout – 10) / 2". The default BS timeout is 130 seconds, so the default BS period =
(130 – 10) / 2 = 60 (seconds)
The BS timeout setting defaults to the value determined by the formula:
BS timeout = BS period × 2 + 10
The default BS period is 60 seconds, so the default BS timeout = 60 × 2 + 10 = 130 (seconds)
