Configuring IPv6 multicast source registration

An IPv6 PIM register policy enables an RP to filter register messages by using an ACL that specifies
the IPv6 multicast sources and groups. The policy limits the multicast groups to which the RP is
designated. If a register message is denied by the ACL or does not match the ACL, the RP discards
the register message and sends a register-stop message to the source-side DR. The registration
process stops.
You can configure the device to calculate the checksum based on the entire register message to
ensure the information integrity of a register message in the transmission process. If a device that
does not support this feature is present on the network, you can configure the device to calculate the
checksum based on the register message header.
The RP sends a register-stop message to the source-side DR in one of the following conditions:
•
The RP stops providing services to the receivers for an IPv6 multicast group. The receivers do
not receive IPv6 multicast data addressed to the IPv6 multicast group through the RP.
•
The RP receives IPv6 multicast data that travels along the SPT.
After receiving the register-stop message, the DR stops sending register messages encapsulated
with IPv6 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 IPv6 multicast data) to
the RP and starts a register probe timer. If the DR receives a register-stop message before the
register probe timer expires, it resets its register-stop timer. Otherwise, the DR starts sending
register messages with encapsulated data again.
The register-stop timer is set to a random
register_suppression_time minus register_probe_time) to (1.5 × register_suppression_time minus
register_probe_time). The register_probe_time is (5 seconds).
On all C-RP routers, perform the following tasks:
•
Configure an IPv6 PIM register policy.
•
Configure the routers to calculate the checksum based on the entire register messages or the
register message header.
On all routers that might become the source-side DR, configure the register suppression time.
