Configuring IP Multicast Routing
Configuring Advanced PIM Features
DETAILED STEPS
To return to the default setting, use the no ip pim spt-threshold {kbps | infinity} global configuration command.
EXAMPLE
The following example shows how to set a threshold of 4 kbps. If the traffic rate exceeds this threshold, the traffic to a
group from a source causes the router to switch to the shortest path tree to that source.
Switch# configure terminal
Switch(config)# ip pim spt-threshold 4
Command Purpose
1. configure terminal Enter global configuration mode.
2. access-list access-list-number {deny
| permit} source [source-wildcard]
Create a standard access list.
 For access-list-number, the range is 1 to 99.
 The deny keyword denies access if the conditions are
matched. The permit keyword permits access if the
conditions are matched.
 For source, specify the multicast group to which the
threshold will apply.
 (Optional) For source-wildcard, enter the wildcard bits
in dotted decimal notation to be applied to the source.
Place ones in the bit positions that you want to ignore.
Recall that the access list is always terminated by an implicit
deny statement for everything.
3. ip pim spt-threshold {kbps | infinity}
[group-list access-list-number]
Specify the threshold that must be reached before moving
to shortest-path tree (spt).
 For kbps, specify the traffic rate in kilobits per second.
The default is 0 kbps.
Note: Because of switch hardware limitations, 0 kbps is the
only valid entry even though the range is 0 to 4294967.
 Specify infinity if you want all sources for the specified
group to use the shared tree, never switching to the
source tree.
 (Optional) For group-list access-list-number, specify
the access list created in Step 2. If the value is 0 or if the
group-list is not used, the threshold applies to all
groups.
4. end Return to privileged EXEC mode.
5. show running-config Verify your entries.
6. copy running-config startup-config (Optional) Save your entries in the configuration file.
