Configuring Multicast Source Registration - HP A6600 Configuration Manual

To do...
2. Enter public network PIM view
or VPN instance PIM view.
3. Configure a C-BSR for an
admin-scope zone.
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.
Configure C-BSRs for the global-scope zone. Complete the following configuration on the routers that you
want to configure as C-BSRs in the global-scope zone.
To do...
1. Enter system view.
2. Enter public network PIM view
or VPN instance PIM view.
3. Configure a C-BSR for the
global-scope zone.
Hash mask length and C-BSR priority
You can configure these parameters at three levels:
• Global configuration level
• Global scope zone level
• Admin-scope zone level
Parameter values configured at the global scope zone level or admin-scope zone level have preference
over the global configuration level values, and default to the global value level.
For configuration of global C-BSR parameters, see

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 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
router 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 method of
checksum calculation.
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 formally starts receiving
register messages with multicast data encapsulated from the multicast source, 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. When the register-stop timer expires, the
