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 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 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.
Description
Use set-overload to set the overload bit.
Use undo set-overload to clear the overload bit.
The overload bit is not set by default.
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.
