>From the release 12.0.R4 Routing Protocols guide:
Syntax overload-on-boot [timeout seconds]
Description When the router is in an overload state, the router is used only if there is no other router to reach the
destination. This command configures the IGP upon bootup in the overload state until one of the following
1. The timeout timer expires.
2. A manual override of the current overload state is entered with the config>router>isis>no overload
The no overload command does not affect the overload-on-boot function.
If no timeout is specified, IS-IS will go into overload indefinitely after a reboot. After the reboot, the IS-IS
status will display a permanent overload state:
L1 LSDB Overload : Manual on boot (Indefinitely in overload)
L2 LSDB Overload : Manual on boot (Indefinitely in overload)
This state can be cleared with the config>router>isis>no overload command.
When specifying a timeout value, IS-IS will go into overload for the configured timeout after a reboot. After
the reboot, the IS-IS status will display the remaining time the system stays in overload:
L1 LSDB Overload : Manual on boot (Overload Time Left : 17)
L2 LSDB Overload : Manual on boot (Overload Time Left : 17)
The overload state can be cleared before the timeout expires with the config>router>isis>no overload command.
The no form of the command removes the overload-on-boot functionality from the configuration.
Default no overload-on-boot
Use show router ospf status and/or show router isis status commands to display the administrative and
operational state as well as all timers.
Parameters timeout seconds - Configure the timeout timer for overload-on-boot in seconds.
Values 60 - 1800

Subject: [alcatel-nsp] how to clear overload-on-boot
this morning we had the issue of a rebooting 7750 which had a overload-on-boot in its isis config.
I failed to find the way to clear the overload.
I instead removed the overload-on-boot and put an overload timeout 60 in the isis config which caused the overload signalling to disappear.
Is there a clear command for overload-on-boot?
