Adjusting Control Parameters for Source Registering

In a PIM-SM network, the DR directly connected to the multicast source encapsulates multicast data in a Register message and sends it to the Rendezvous Point (RP) in unicast mode. The RP then decapsulates the message, and forwards the multicast data to receivers along the rendezvous point tree (RPT). The system supports the Register message filtering and suppression functions.

Configuring PIM-SM Register Messages: You can configure filtering policies for Register messages on all the devices that may become Rendezvous Points (RPs). By default, the checksum is calculated based on the entire Register message. You can configure the device to calculate the checksum based on only the header of a Register message.

Configuring PIM-SM Register Suppression: You can set the timeout period for keeping the register suppression state and the interval for sending null Register messages on all the devices that may become DRs at the multicast source side.

(Optional) Specifying the Source Address for Sending Register Messages: Specify the source address for sending Register messages on all devices that may become source's DRs. In this manner, registration errors will not occur due to repeated IP addresses on the network or filtered IP addresses.
