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...

Use the command...

z

Generally, a smaller distance from the filter to the IPv6 multicast source results in a more

remarkable filtering effect.

z

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.
