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:
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:
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

Command Purpose
Router(config-router)# lsp-gen-interval [level-1 |
level-2] lsp-max-wait [lsp-initial-wait
lsp-second-wait]
Sets IS-IS LSP generation throttling timers.
• The default lsp-max-wait interval is 5 seconds.

• The default lsp-second-wait interval is 5000
milliseconds.
Router(config-router)# spf-interval [level-1 |
level-2] spf-max-wait [spf-initial-wait
spf-second-wait]
Sets IS-IS SPF throttling timers.
• The default spf-max-wait interval is 10 seconds.
• The default spf-initial-wait interval is
5500 milliseconds.
• The default spf-second-wait interval is 5500
milliseconds.
Router(config-router)# prc-interval prc-max-wait
[prc-initial-wait prc-second-wait]
Sets IS-IS partial route computation throttling timers.
• The default prc-max-wait interval is 10 seconds.
• The default prc-initial-wait interval is 2000
milliseconds.
• The default prc-second-wait interval is 5000
milliseconds.
Command Purpose
Router# isis display delimiter [return count |
character count]
Specifies the delimiter to be used to separate displays of
information about individual IS-IS areas.
