PIM common feature configuration task list

Task

Configuring a multicast data filter

Configuring a hello message filter
Configuring PIM hello options
Configuring the prune delay
Configuring PIM common timers
Configuring join/prune message sizes
Setting the DSCP value for PIM messages

Configuration prerequisites

Before you configure 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 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 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.
•
Determine the DSCP value for PIM messages.
•
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 on one
hand, and control the information available to receivers downstream to enhance data security on the
other hand.
