Configuration prerequisites
Before you configure common PIM features, complete the following tasks:
• Configure any unicast routing protocol so that all devices in the domain are interoperable at the
network layer.
• Configure PIM-DM, or PIM-SM, or PIM-SSM.
• Determine the ACL rule for filtering multicast data.
• Determine the ACL rule defining a legal source address range for hello messages.
• Determine the priority for DR election (global value/interface level value).
• Determine the PIM neighbor timeout timer (global value/interface value).
• Determine the prune message delay (global value/interface level value).
• Determine the prune override interval (global value/interface level value).
• Determine the prune delay.
• Determine the hello interval (global value/interface level value).
• Determine the maximum delay between hello message (interface level value).
• Determine the assert timeout timer (global value/interface value).
• Determine the join/prune interval (global value/interface level value).
• Determine the join/prune timeout (global value/interface value).
• Determine the multicast source lifetime.
• Determine the maximum size of join/prune messages.
• Determine the maximum number of (S, G) entries in each join/prune message.
Configuring 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.
To configure a multicast data filter:

No multicast data filter by default.
This filter works not only on independent
multicast data but also on multicast data
encapsulated in register messages.
