Configure C-BSRs for each admin-scope zone and the global-scope zone.
1. Configure C-BSRs for each admin-scope zone
Perform the following configuration on the routers that you want to configure as C-BSRs in admin-scope
zones.
Follow these steps to configure a C-BSR for an admin-scope zone:
To do… Use the command… Remarks
Enter system view system-view —
Enter public network PIM view or
VPN instance PIM view pim [ vpn-instance
vpn-instance-name ]
—
Configure a C-BSR for an
admin-scope zone
c-bsr group group-address { mask |
mask-length } [ hash-length
hash-length | priority priority ] *
Required
No C-BSRs are configured for an
admin-scope zone by default.
NOTE:
The group-address { mask | mask-length } parameter of the c-bsr group command can specify the
multicast groups the C-BSR serves, in the range of 239.0.0.0/8.
2. Configure C-BSRs for the global-scope zone
Perform the following configuration on the routers that you want to configure as C-BSRs in the
global-scope zone.
Follow these steps to configure a C-BSR for the global-scope zone:
To do… Use the command… Remarks
Enter system view system-view —
Enter public network PIM view or
VPN instance PIM view pim [ vpn-instance
vpn-instance-name ]
—
Configure a C-BSR for the
global-scope zone c-bsr global [ hash-length
hash-length | priority priority ] *
Required
No C-BSRs are configured for the
global-scope zone by default.
NOTE:
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 will be used.
For configuration of global C-BSR parameters, see “ Configuring global C-BSR parameters .”
