6.5.2 Configuration Prerequisites
Before configuring PIM common information, 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 information, prepare the following data:
z
An ACL rule as multicast data filter
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
6.5.3 Configuring a PIM 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.
