Typically, you need to configure the above-mentioned parameters on the receiver-side DR and the RP
only. Since both the DR and RP are elected, however, you should carry out these configurations on the
routers that may win DR election and on the C-RPs that may win RP election.

Configuring a Multicast Data Filter
No matter in a PIM-DM domain or a PIM-SM domain, routers can check passing-by multicast data
based on the configured filtering rules and determine whether to continue forwarding the multicast data.
In other words, PIM routers can act as multicast data filters. These filters can help implement traffic
control on one hand, and control the information available to receivers downstream to enhance data
security on the other hand.
Follow these steps to configure a multicast data filter:

z If you have configured a basic ACL, the switch filters all the received multicast packets based on
the multicast source address, and discards packets that fail source address match.
z If you have configured an advanced ACL, the switch filters all the received multicast packets based
on the multicast source address and group address, and discards packets that fail source and
group address match.
