DETAILED STEPS
Purpose
Command or Action
Enables privileged EXEC mode.
enable
Step 1
Example:
Device>
enable
•
Enter your password if prompted.
Enters global configuration mode.
configure terminal
Example:
Device#
configure terminal
Step 2
Creates a standard access list.
access-list access-list-number
{
deny
|
permit
}
source
[
source-wildcard
]
Step 3
•
For
access-list-number
, the range is 1 to 99.
Example:
Device(config)#
access-list 16 permit
•
The
deny
keyword denies access if the conditions are matched.
•
The
permit
keyword permits access if the conditions are matched.
225.0.0.0 0.255.255.255
•
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.
The access list is always terminated by an implicit deny statement for
everything.
Specifies the threshold that must be reached before moving to
shortest-path tree (spt).
ip pim spt-threshold
{
kbps
|
infinity
}
[
group-list access-list-number
]
Step 4
Example:
Device(config)#
ip pim spt-threshold
•
For
kbps
, specify the traffic rate in kilobits per second. The default
is 0 kbps.
Because of device hardware limitations, 0 kbps is the only
valid entry even though the range is 0 to 4294967.
Note
infinity group-list 16
•
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.
