Configuring Integrated IS-IS

Miscellaneous IS-IS Parameters Configuration Task List

Other commands are available to control the delay between successive LSPs, the retransmission of the same LSA, and the retransmission of LSPs on a point-to-point interface.

Perform this task to customize throttling of LSP generation, SPF calculation, PRC, or any combination of the three, beginning in router configuration mode:

Command	Purpose
Router(config-router)# lsp-gen-interval[level-1	Sets IS-IS LSP generation throttling timers.
level-2]lsp-max-wait [lsp-initial-wait	• The default lsp-max-waitinterval is 5 seconds.
lsp-second-wait]
	• The default lsp-initial-waitinterval is 50 milliseconds.
	• The default lsp-second-waitinterval is 5000
	milliseconds.
Router(config-router)# spf-interval[level-1	Sets IS-IS SPF throttling timers.
level-2]spf-max-wait [spf-initial-wait	• The default spf-max-waitinterval is 10 seconds.
spf-second-wait]
	• The default spf-initial-waitinterval is
	5500 milliseconds.
	• The default spf-second-waitinterval is 5500
	milliseconds.
Router(config-router)# prc-intervalprc-max-wait	Sets IS-IS partial route computation throttling timers.
[prc-initial-wait prc-second-wait]	• The default prc-max-waitinterval is 10 seconds.
	• The default prc-initial-waitinterval is 2000
	milliseconds.
	• The default prc-second-waitinterval is 5000
	milliseconds.

Modifying the Output of show Commands

To customize display output when the IS-IS multiarea feature is used, making the display easier to read, use the following command in EXEC mode:

Command	Purpose
Router# isis display delimiter [return count	Specifies the delimiter to be used to separate displays of
character count]	information about individual IS-IS areas.

For example, the following command causes information about individual areas to be separated by

14 dashes (-) in the display:

isis display delimiter - 14

The output for a configuration with two Level 1 areas and one Level 2 area configured is as follows:

dtp-5#show clns neighbors

Area L2BB:
System Id	Interface	SNPA	State	Holdtime	Type Protocol
0000.0000.0009	Tu529	172.21.39.9	Up	25	L1L2 IS-IS
