787BConfiguring a multicast data filter
In either 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 and
also control the information available to downstream receivers to enhance data security.
Generally, a smaller distance from the filter to the multicast source results in a more remarkable filtering
effect.

No multicast data filter by default.
This filter works not only on independent
multicast data but also on multicast data
encapsulated in register messages.
788BConfiguring a hello message filter
Along with the wide applications of PIM, the security requirement for the protocol is becoming
increasingly demanding. The establishment of correct PIM neighboring relationship is the prerequisite for
secure application of PIM.
To guard against PIM message attacks, you can configure a legal source address range for hello
messages on interfaces of routers to ensure the correct PIM neighboring relationship.
