3. Configure a PIM domain
border.
Configuring global C-BSR parameters
In each PIM-SM domain, a unique BSR is elected from C-BSRs. The C-RPs in the PIM-SM domain send
advertisement messages to the BSR. The BSR summarizes the advertisement messages to form an RP-set
and advertises it to all routers in the PIM-SM domain. All the routers use the same hash algorithm to get
the RP address that corresponds to specific multicast groups.
To do...
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.
You can configure the hash mask length and C-BSR priority globally, in an admin-scope zone, and in the
global scope zone.
The values configured in the global scope zone or admin-scope zone have preference over the
•
global values.
• If you do not configure these parameters in the global scope zone or admin-scope zone, the
corresponding global values are used.
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.
