All the routers use the same Hash algorithm to get the RP address corresponding to the specific multicast
group.
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 will work 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 pim —
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 will work 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 pim —
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:
About the Hash mask length and C-BSR priority:
• You can configure these parameters at three levels: global configuration level, global scope zone
level, and admin-scope zone level.
• The value of these parameters configured at the global scope zone level or admin-scope zone
level have preference over the global values.
• If you do not configure these parameters at the global scope zone level or admin-scope zone
level, the corresponding global values will be used.
For configuration of global C-BSR parameters, see Configuring global C-BSR parameters .
Configuring Multicast Source Registration
Within a PIM-SM domain, the source-side DR sends register messages to the RP, and these register
messages have different multicast source or group addresses. You can configure a filtering rule to filter
register messages so that the RP can serve specific multicast groups. If an (S, G) entry is denied by the
