Configuring multicast source registration

A PIM register policy enables an RP to filter register messages by using an ACL that specifies the 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 switch to calculate the checksum based on the entire register message to ensure information integrity of a register message in the transmission process. If a device that does not support this feature is present on the network, configure the switch to calculate the checksum based on the register message header.
