Section 13.6.7.2
Adding an LSP Generation Interval
To add an LSP generation interval to an IS-IS area, do the following:
1. Make sure the CLI is in Configuration mode.
2. Add a new interval by typing:
routing isis area name lsp-gen-interval is-type [ level-1-2 | level-1-only | level-2-only ]
interval seconds
Where:
•
name
is the unique name for a routing process that belongs to a specific router.
•
level
is the IS type.
•
seconds
is the minimum interval in seconds, ranging from 1 to 120. The default value is 30.
3. Type commit and press Enter to save the changes, or type revert and press Enter to abort.

Section 13.6.8
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.
