Step
1. Enter system view.
2. Enter public network PIM view
or VPN instance PIM view.
3. Configure an interface as a
C-BSR.
4. Configure a legal BSR
address range.
Configuring a PIM domain border
As the administrative core of a PIM-SM domain, the BSR sends the collected RP-Set information in the
form of bootstrap messages to all routers in the PIM-SM domain.
A PIM domain border is a bootstrap message boundary. Each BSR has its specific service scope. A
number of PIM domain border interfaces partition a network into different PIM-SM domains. Bootstrap
messages cannot cross a domain border in either direction
Perform the following configuration on routers that you want configure as a PIM domain border.
To configure a PIM domain border:
Step
1. Enter system view.
2. Enter interface view.
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 corresponding to specific multicast groups.
You can configure the hash mask length and C-BSR priority globally, in a admin-scoped zone, and/or in
the global-scoped zone.
The values configured in the global-scoped zone or admin-scoped zone have preference over the
•
global values.
If you do not configure these parameters in the global-scoped zone or admin-scoped zone, the
•
corresponding global values will be used.
For configuration of C-BSR parameters for an admin-scoped zone and global-scoped zone, see
"Configuring a C-BSR for each admin-scoped zone and the global-scope
Perform the following configuration on C-BSR routers.
