In configuration, make sure that the BS period is smaller than the BS timeout value.

Configuring IPv6 Multicast Source Registration

Within an IPv6 PIM-SM domain, the source-side DR sends register messages to the RP, and these

configure a filtering rule to filter register messages so that the RP can serve specific IPv6 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

IPv6 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 data addressed to a certain IPv6 multicast group through the RP (that is,

the RP stops serving the receivers of that IPv6 multicast group), or when the RP formally starts

receiving IPv6 multicast data from the IPv6 multicast source, the RP sends a register-stop message to

the source-side DR. Upon receiving this message, the DR stops sending register messages

encapsulated with IPv6 multicast data and starts a register-stop timer. When 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 probe time, it will reset its

when the register-stop timer expires.

The Register-Stop Timer is set to a random value chosen uniformly from the interval (0.5 times

register_suppression_time, 1.5 times register_suppression_time) minus register_probe_time.

Configure a filtering rule for register messages on all C-RP routers and configure them to calculate the

checksum based on the entire register messages. Configure the register suppression time and the
