Configuration Prerequisites
Before configuring PIM common features, complete the following tasks:
z
Configure any unicast routing protocol so that all devices in the domain are interoperable at the
network layer.
z
Configure PIM-DM, or PIM-SM, or PIM-SSM.
Before configuring PIM common features, prepare the following data:
z
An ACL rule for filtering multicast data
z
An ACL rule defining a legal source address range for hello messages
z
Priority for DR election (global value/interface level value)
z
PIM neighbor timeout time (global value/interface value)
z
Prune delay (global value/interface level value)
z
Prune override interval (global value/interface level value)
z
Hello interval (global value/interface level value)
z
Maximum delay between hello message (interface level value)
z
Assert timeout time (global value/interface value)
z
Join/prune interval (global value/interface level value)
z
Join/prune timeout (global value/interface value)
z
Multicast source lifetime
z
Maximum size of join/prune messages
z
Maximum number of (S, G) entries in a join/prune message
Configuring a Multicast Data Filter
No matter in 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 on one hand, and control the information available to receivers downstream to enhance data
security on the other hand.
Follow these steps to configure a multicast data filter:
