For configuration of global C-BSR parameters, see "Configuring global C-BSR parameters."
Configure C-BSRs for each admin-scoped zone and the global-scoped zone.
Perform the following configuration on the routers that you want to configure as C-BSRs in admin-scoped
zones.
To configure a C-BSR for an admin-scoped zone:

Command Remarks
1. Enter system view.
system-view N/A
2. Enter public network PIM view.

3. Configure a C-BSR for an
admin-scoped zone.
c-bsr group group-address
{ mask | mask-length }
[ hash-length hash-length |

No C-BSRs are configured for an
admin-scoped zone by default.
The group-address { mask |
mask-length } argument can specify the
multicast groups that the C-BSR serves,
in the range of 239.0.0.0/8.

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 the filtering rule denies an (S, G)
entry, or if the filtering rule does not define the action for this entry, the RP will send a register-stop
message to the DR to stop the registration process for the multicast data.
In view of information integrity of register messages in the transmission process, you can configure the
device to calculate the checksum based on the entire register messages. However, to reduce the
workload of encapsulating data in register messages and for the sake of interoperability, do not use this
checksum calculation method.
When receivers stop receiving multicast data addressed to a certain multicast group through the RP (that
is, the RP stops serving the receivers of that multicast group), or when the RP starts receiving multicast
data from the multicast source along the SPT, the RP sends a register-stop message to the source-side DR.
After receiving this message, the DR stops sending register messages encapsulated with multicast data
and starts a register-stop timer. Before the register-stop timer expires, the DR sends a null register message
(a register message without encapsulated multicast data) to the RP. If the DR receives a register-stop
