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.
