Section 5.18.8
Managing SPF Calculations
IS-IS uses the Shortest Path First (SPF) algorithm to determine the best routes to every known destination in the
network. When the network topology (not external links) changes, a partial recalculation is required.
IS-IS can be configured to perform the SPF calculation every 1 to 120 seconds. By default, IS-IS performs the
SPF calculation every second. which could potentially be processor intensive, depending on the size of the area
and how often the topology changes.
The following sections describe how to configure and manage SPF calculations for IS-IS areas:
•
Section 5.18.8.1, "Viewing a List of SPF Calculation Intervals"
•
Section 5.18.8.2, "Adding an SPF Calculation Interval"
•
Section 5.18.8.3, "Deleting an SPF Calculation Interval"
Section 5.18.8.1
Viewing a List of SPF Calculation Intervals
To view a list of SPF calculation intervals configured for an IS-IS area, type:
show running-config routing isis area name spf-interval
Where:
• name is the unique name for a routing process that belongs to a specific router.
If intervals have been configured, a table or list similar to the following example appears:
