Configuring an IPv6 Multicast Data Filter

No matter in 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 on one hand, and control the information available to downstream
receivers to enhance data security on the other hand.
Follow these steps to configure an IPv6 multicast data filter:
To do...
Enter system view
Enter IPv6 PIM view
Configure an IPv6 multicast
group filter
Generally, a smaller distance from the filter to the IPv6 multicast source results in a more
remarkable filtering effect.
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
more and more demanding. The establishment of correct IPv6 PIM neighboring relationships is a
prerequisite for secure application of IPv6 PIM. You can configure a legal source address range for hello
messages on interfaces of routers to ensure the correct IPv6 PIM neighboring relationships and thus to
guide against IPv6 PIM message attacks.
Follow these steps to configure a hello message filter:
Use the command...
system-view
pim ipv6
source-policy acl6-number
1-28
