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.
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.
To configure an IPv6 multicast data filter:
Step
1. Enter system view.
2. Enter IPv6 PIM view.
3. Configure an IPv6 multicast
group filter.
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.
