Configuration Guide - Multicast
Applicable Environment
This configuration is applicable to all PIM-DM networks.
A PIM switch checks the passing multicast data. By checking whether the data matches the
filtering rule, the switch determines whether to forward the data. In this case, you can regard the
switch as the filter of the multicast data. The filter helps to control the data flow and limit the
information that downstream receivers can obtain. Network security is thus ensured.

considers that the (S, G) entry becomes invalid and the multicast source stops sending multicast
data to the multicast group.
