Configuring an IPv6 multicast data filter
In either an IPv6 PIM-DM domain or an IPv6 PIM-SM domain, routers can check passing-by IPv6 multicast
data based on the configured filtering rules and determine whether to continue forwarding the IPv6
multicast data. In other words, IPv6 PIM routers can act as IPv6 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 IPv6 multicast source results in a more remarkable
filtering effect.
To configure an IPv6 multicast data filter:

No IPv6 multicast data filter by
default.
This filter works not only on
independent IPv6 multicast data
but also on IPv6 multicast data
encapsulated in register messages.
Configuring a hello message filter
Along with the wide applications of IPv6 PIM, the security requirement for the protocol is becoming
increasingly demanding. The establishment of correct IPv6 PIM neighboring relationship is a prerequisite
for secure application of IPv6 PIM.
To guard against IPv6 PIM message attacks, you can configure a legal source address range for hello
messages on interfaces of routers to ensure the correct IPv6 PIM neighboring relationship.
To configure a hello message filter:
