To disable default route generation, use the no default-information originate router configuration
command. Use the no area-password or no domain-password router configuration command to disable
passwords. To disable LSP MTU settings, use the no lsp mtu router configuration command. To return
to the default conditions for summary addressing, LSP refresh interval, LSP lifetime, LSP timers, SFP
timers, and PRC timers, use the no form of the commands. Use the no partition avoidance router
configuration command to disable the output format.

Configuring IS-IS Interface Parameters

You can optionally configure certain interface-specific IS-IS parameters, independently from other
attached routers. However, if you change some values from the defaults, such as multipliers and time
intervals, it makes sense to also change them on multiple routers and interfaces. Most of the interface
parameters can be configured for level 1, level 2, or both.

Purpose
(Optional) Sets IS-IS shortest path first (SPF) throttling timers.
• spf-max-wait—the maximum interval between consecutive SFPs (in
seconds). The range is 1 to 120, the default is 10.
• spf-initial-wait—the initial SFP calculation after a topology change (in
milliseconds). The range is 1 to 10000; the default is 5500.
• spf-second-wait—the holdtime between the first and second SFP
calculation (in milliseconds). The range is 1 to 10000; the default is
5500.
(Optional) Sets IS-IS partial route computation (PRC) throttling timers.
• prc-max-wait—the maximum interval (in seconds) between two
consecutive PRC calculations. The range is 1 to 120; the default is 5.
• prc-initial-wait—the initial PRC calculation delay (in milliseconds)
after a topology change. The range is 1 to 10,000; the default is 2000.
• prc-second-wait—the hold time between the first and second PRC
calculation (in milliseconds). The range is 1 to 10,000; the default is
5000.
(Optional) Set the router to log IS-IS adjacency state changes. Enter all to
include all changes generated by events that are not related to the
Intermediate System-to-Intermediate System Hellos, including End
System-to-Intermediate System PDUs and link state packets (LSPs).
(Optional) Specify the maximum LSP packet size in bytes. The range is 128
to 4352; the default is 1497 bytes.
Note If any link in the network has a reduced MTU size, you must change
the LSP MTU size on all routers in the network.
(Optional) Causes an IS-IS Level 1-2 border router to stop advertising the
Level 1 area prefix into the Level 2 backbone when full connectivity is lost
among the border router, all adjacent level 1 routers, and end hosts.
Return to privileged EXEC mode.
Verify your entries.
(Optional) Save your entries in the configuration file.
