Use
undo set-overload
to clear the overload bit.

Parameters
on-startup
: Sets the overload bit upon system startup.
start-from-nbr
system-id
[
timeout1
[
nbr-timeout
] ]: Starts the
nbr-timeout
timer when the router begins
to establish the neighbor relationship with the neighbor after system startup. If the neighbor relationship
is formed within the
nbr-timeout
interval, IS-IS keeps the overload bit set. If not, the bit is cleared. IS-IS
keeps the overload bit set within the
timeout1
interval after the neighbor relationship is formed within the
nbr-timeout
interval.
•
system-id
—Specifies the neighbor.
•
timeout1
—The
timeout1
interval is in the range of 5 to 86400 seconds and defaults to 600
seconds.
•
nbr-timeout
—The timer has an interval from 5 to 86400 seconds. The default is 1200 seconds.
timeout2:
Sets the overload bit within the
timeout2
interval after system startup. The interval is in the
range of 5 to 86400 seconds and defaults to 600 seconds.
allow
: Allows advertising address prefixes. By default, no address prefixes are allowed to be advertised
when the overload bit is set.
external
: Allows advertising IP address prefixes redistributed from other routing protocols with the
allow
keyword specified.
interlevel
: Allows advertising IP address prefixes learned from different IS-IS levels with the
allow
keyword specified.
Usage guidelines
If the
on-startup
keyword is not specified, the command sets the overload bit immediately until the
undo
set-overload
command is executed.
If the
on-startup
keyword is specified, IS-IS sets the overload bit upon system startup and keeps it set
within the
timeout2
interval.
Examples
# Set overload flag on the current router.
