Configuration prerequisites
Before you configuring PIM common 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 for filtering multicast data.
• Determine the ACL 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 time (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 time (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 a join/prune message.
Configuring a multicast data filter
In either a PIM-DM domain or a PIM-SM domain, routers can examine passing-by multicast data based
on the configured filtering rules and determine whether to continue forwarding the multicast data. 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.
Follow these steps to configure a multicast data filter:
