Configuring Multicast Source Registration - HP A8800 Configuration Manual

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:
Step
1. Enter system view.
2. Enter public network PIM view
or VPN instance PIM view.
3. Configuring a C-BSR for an
admin-scoped zone.

Perform the following configuration on the routers that will you want to configure as C-BSRs in the
global-scope zone.
To configure a C-BSR for the global-scope zone:
Step
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.

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
filtering rule, or the action for this entry is not defined in the filtering rule, 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, this method of
checksum calculation is not recommended.
When receivers stop receiving multicast data addressed to a certain multicast group through the RP
(which means the RP stops serving the receivers of that multicast group), or when the RP starts receiving
register messages with multicast data encapsulated from the multicast source along the SPT, the RP sends
a register-stop message to the source-side DR. Upon 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 message during the register

No C-BSRs are configured for an

The group-address { mask |

multicast groups the C-BSR serves,
in the range of 239.0.0.0/8.
